On the Rights of Rocks to Stay or to Go

IMG_0285

Yesterday, a strange incident occurred here in Stamford Hill. It was somewhere after midnight when there was suddenly a loud shattering of glass in the room. No one was hurt, but the whole room was covered in small glass fragments, even in the bookshelves. We had been facing the other wall when it happened. We looked at the lightbulbs to see if they had blown, but in the end discovered the source of all the broken glass was a gaping hole in the window. Somebody or something had broken the window with some projectile. We could not ascertain if it had been a rock or a pellet gun or something more sinister, so we called the police to let them know - just in case it had been a serial incident in the area.

After we had called the police, we discovered a small half-rock on the sofa. By half-rock I mean a rock that looked like it had been shattered into two by a hammer. Unfortunately, as people who have been following my blog or my work will know, I collect rocks (and half-rocks in particular). This is probably the first time that I've discovered any downside to being a rock collector, and that would be: Not being sure if the rock on the sofa is the projectile that someone just used to break the window - or just another a rock from your rock collection?...

Example: Thames River half-rocks from my rock collection

So when Hackney police called back (and came by to file the report), we told them about the rock but with the caveat that that one of us was a rock collector and could not tell for sure if it was our rock or the offending projectile. This did, however, prompt me to take out my bag full of Thames rocks and Paris rocks and I examined all of them. Based on its appearance, it seemed like it could conceivably be one of my rocks… but what would it be doing in the sofa that we frequently dusted off and rearranged? It was a far leap from G's mantlepiece. And the angle was all wrong for it to have come from the hole in the window…

"You can go ahead and touch the rock," the policeman said when he came around, "we can't take fingerprints on rocks or test for minerals or fibers, or that sort of thing." Good thing to know next time you need to commit a crime with a rock... They ain't gonna to be able to do much forensics with it after all...

Later that night, after we had picked up most of the glass off the carpet, I decided to pick up and read The Book of Books which I picked up at dOCUMENTA(13). The book itself is ridiculously huge (23 x 6.1 x 28 cm) and heavy (2.5kg), so I have been deliberating on whether to take the book back to Singapore in my check-in luggage.

Since I can't take an infinite amount of things in my luggage, I've taken the precautions of mailing back parcels of the large and heavy items I had accumulated over the last few months. Recently, I also shipped back a number of very heavy slabs of pavement rocks from Paris - rocks that technically had no value except that they were pavement rocks that I had collected by hand and exhibited in a show. People have been asking me whether I would bring the rocks back to Singapore - and I did think for a very long time about whether I should remove them from their country of origin. But there was no conceivable way that I could leave them there where I had found them, where no one would know their significance to me; how could I ever justify throwing them out? So, I was compelled to take them with me, no matter what. But 20kg of rocks is very expensive to ship from France to Singapore. Firstly, without the help of Elio I would never have been able to even shift them to the post office as they were too heavy for me to carry on my own; and secondly, as it was to be expected, it was enormously expensive to ship them back to Singapore: the resultant shipping for 20kg of rocks cost a few hundred Euros… and on top of that, they are still somewhere lost in transit as we speak… I suppose 20kg of rocks in a cardboard wrapping would look pretty suspicious…

IMG_7998

The weight of these items - which prevents them from being physically transported in a convenient or casual fashion - also gives them certain import. For example, after all these travels about Europe, I know for a certainty now that any single piece of luggage exceeding 28kg is physically impossible for me to lift - or so much as feebly drag along the ground, no matter how much I desire it. The truth of the matter is that it is physically impossible for me to lift any piece of luggage that is heavier than 28kg. If I had found a rock that was 28kg heavy, there would be absolutely no question of asking if I would carry the rock home with me because it would not be physically possible to do so in the first place.

I read Carolyn Christov-Bakargiev’s opening essay to The Book of Books with much interest because it involves a story about another abortive attempt to move a very big rock. She writes about one of the few projects that was publicly announced but eventually did not come to fulfillment at dOCUMENTA(13) - the proposal by Argentinian artists Guillermo Faivovich and Nicholas Goldberg to bring El Chaco, the second largest meteorite in the world, from its original resting place north of Argentina, to a temporary location in Kassel that would have been not far from Walter De Maria's Vertical Earth Kilometre (a metal rod of 5cm diameter that appears as a flat circular disc when viewed from the top but which goes 1km deep into the ground).

Apparently Argentine law prohibits the removal of any of the meteorite fragments from the Chaco province, but had made a turn-around and approved the move of El Chaco specifically for the purposes of documents, with the provincial government citing it as a chance to spread awareness of the impoverished area of Chaco and its meteorites. However, there was opposition to the move from the aboriginal Moqoit natives for whom the El Chaco is a sacred monument, backed by scientists, some of whom have written passionately on the issue.

As quoted in many articles, one of the most outspoken of letters is from a social anthropologist Alejandro López who wrote: "We firmly believe that this project implies a deeply colonialist attitude, wherein the artists’ desire is to link themselves with the wealth and valuables of the Chaco. Instead of this “transfer” of the meteorite as a sort of “cosmic curiosity,” it would be preferable for those who have the money and prestige to seek to promote the value of the meteorite within its place of origin."

Searching for other articles on El Chaco, I have to admit that I found it somewhat maddening that most if not all of the news reports follow in the same tone as the letter above, condemning the artists' intentions as "colonial" or upholding some manner of "deeply colonial attitudes" towards the ways in which "cultural objects" are to be handled.

An AFP report has the headline: "An unlikely alliance between the native Moqoit people and leading Argentine scientists has thwarted plans to ship the world's second largest meteorite to Germany as a prestigious art exhibit."

Thwarted! As if the artists were an evil and cruel money-grubbing force trying to steal the rock from the poor poor natives! No doubt, it remains indefensible that the artists failed to consult the Moqoit before submitting the proposal, and that past attempts by colonialists to steal their meteorites (because it was made of metal) have left "serious cultural damage" and left the Moqoit with a legacy of "suspicion and insecurity" towards anyone who should make advances on their rock.

But to chalk every subsequent proposal to move El Chaco down to an act of colonialism is surely just as much subjugating the Moquoi natives and forcing them to keep playing the role of "victim" -- trapped within the old colonised-vs-colonialist mindset!

To cry "colonialist" is like falling into the trap of the "anti-colonial" stance; it perpetuates the old narratives of imperialism, colonialism, conquest, oppression, emancipation, etc; it expects that the stories should play out as power struggles between the oppressed and the oppressor; it expects that everyone in the world still has identities fixed by cultural or geographical origins; it expects that artists should make works which then have to be explained from their country of origin or socio-economic background or upbringing. And that is just so... boring.

Carolyn Christov-Bakagiev: "And what if we asked ourselves, beyond this irresolvable contradiction, what it was to see things from the position of the meteorite? It had travelled through vertiginous space before landing on Earth and settling. Would it have wished to go on this further journey? Does it have any rights, and if so, how can they be exercised? Can it asked to be buried again, as some of the Moqoit argue, or would it have enjoyed a short trip to an art exhibition, rather than a science or world's fair? (…) What is this displaced position, generated by the perception of a simultaneous being in different spaces, where the collapse of time and distance provokes a new sense of what it means to be always in one place, and not in another place?"

Primavera évoque bien sûr le printemps, et aussi les (re)-commencements. Qu’est-ce qu’être un artiste qui recommence ailleurs ? Comment habiter un espace où je ne fais que passer sans tomber dans la standardisation ? Comment intégrer le lieu d’accueil et créer mon propre chemin à l’intérieur d’une forêt de signes étrangers ? Comment manipuler l’iconographie pour sortir de mon propre folklore ? Comment Paris me met en mouvement ? Comment procéder à l’élagage, au transcodage, à la traduction ?

Geocoding: From Excel to TileMill (Part II)

This continues from the previous post, where the iPhone GPS data has been batch exported to Excel BUT in a weird DMS format rather than the DD format that we need in order to import into TileMill. Unfortunately, there is no magic button or plugin for this, but in the end... it turns out... its not that hard after all. Doh.

D + M/60 + S/3600 = DD
In Excel:
=SUM([@[D-Lat]]+[@[M-Lat]]/60+[@[S-Lat]]/3600)
=SUM([@[D-Lon]]+[@[M-Lon]]/60+[@[S-Lon]]/3600)

Note that iPhone's format may actually be D,M(in decimals) without an S value.

Screen Shot 2012-11-08 at 10.36.40 AM.png

Degree:Minutes:Seconds GPS values converted to Decimal Degrees!
(See Lat and Lon column. TileMill will understand any of the following column headers: latitude, longitude, lat, long,lon, x, y.)

Data successfully imported into TileMill Layer!

Plotted successfully! But what is this? IT IS ALL EMPTY!?????

Oh so I forgot to add in any shape layers. So next we need an ESRI Shapefile for city of Paris available here here and here from metro.teczno.com and downloads.cloudmade.com respectively, based on OpenStreetMap data. [See also: Adding Layers in TileMill]

Successful loading of shape layers for buildings and main roads.
Some random slapbang colours here just for testing purposes.

SUCCESS!!!

Now I will finetune it from here...

Geocoding: From the streets to Adobe Bridge and then Excel (Part I)

This is a documentation post for my own record on how I will produce a map of 180 date points that I have collected so far. To be honest I'm not a real programmer or anything like that, so the methods used in this post might be desultory or silly. I'm helplessly flapping about here. I'd be happy to hear of what method others would use! But in the absence of any external assistance........

So the situation thus far is that all the images I have taken have been geotagged by default in iPhone 4, and I want to pull the metadata out into csv (comma separated values) and then bring into something like TileMill where I can produce a proper map of it all.

Screen Shot 2012-11-08 at 6.49.15 AM.png

Viewing Metadata in Adobe Bridge

But first, the drudgery. I needed to batch export the filenames and gps data from all my images. Unfortunately there was no instant readymade solution for this online that I could immediately find. Like with Illustrator and Flash's automation scripts, what I ended having to do was to write a simple Adobe Bridge script to export all the information...

To find the location for your Bridge scripts, go to Preferences > Click on "Reveal My Startup Scripts" to see the folder in Finder. I found a script on a forum and adapted it slightly (quick and dirty) to include the GPS data. Save it as a .jsx file and drop it into the Startup Scripts folder. Because Bridge is silly, you will have to close and reopen Bridge in order for the script to load - apparently you can't load it on the fly while Bridge is open. With this script, a new menu item will appear under tools: "Export CSV file"

Screen Shot 2012-11-08 at 7.09.29 AM.png

Export to CSV

For some reason, iPhone's geodata is formatted in degrees:minutes:seconds rather than decimal degrees, and on top of that - confusingly º (degree) is replaced by comma and minutes by full stop, e.g:

48,49.8N 2,22.13E

I wonder why that is so by default. I suppose I understand it but let me tell you if you just plug this into TileMill it wont be read because of the wrong delimiters and I suspect it also requires decimal degrees (DD) instead of degrees-minutes-seconds (DMS). Cue the furious googling of "HOW DOES I CONVERT DMS TO DD?"

Anyway back to the batch exporting of metadata to Excel. The data is saved in different namespaces such as the "exif" and "photoshop" data. EXIF stands for Exchangeable image file format and this is the format for the storage of metadata in files such as images and also audio files. You need to invoke the right namespace to find the right property. For example I realised that the Date Created in both exif and photoshop are different because only files that have been edited within photoshop have got a Date Created stamp (do note the property names also differ slightly in syntax although they may describe similar types of properties).

I eventually figured out which namespace the gps data resided in (EXIF). I don't know why it isn't more straightforward to find a reference for all these things. Anyway since we are on the topic, this is a list of standard Namespaces; from these different namespaces you can search for the properties you are looking for so you can call them up:

"Telepathy" / "Pedestrian Racing" (Documentation of Work, Goodman Arts Centre, Sept 2012)

gac floorplan mockup

I just recalled that on the eve of my departure from Singapore I had spent some time scurrying around the Goodman Arts Centre applying some vinyls to the ground in anticipation of this year's Goodman Arts Centre Open House. Although I was not in Singapore at the time to see people's responses or interactions with it, I hope that someone out there actually saw it.

Here are two psychogeographical games presented by the Singapore Psychogeographical Society + Studio Thirteen at the GAC Open House 2012 - "Telepathy" and "Pedestrian Racing" - located at the 3rd, 4rd, and 5th floors of Block B, based on the fact that the upper floors of Block B offer a kind of panopticonic view of the entire compound and everyone walking in...:

Installation

If attempting the foolhardy task of applying many vinyl text to the ground by oneself, do check at the printer if they have missed out any dots or the letter i. Next, clean the ground with a rag rather than pouring a bucket onto it or it will TAKE HOURS TO DRY. These were things I wish I knew before I had to cut out my own dots for letters, and before I gaily tossed a bucket of water on the ground and had to wait a few hours for it to dry - hours which I could scarcely afford on what was literally the eve of my departure. In the end, I ran out of time and part of the installation had to be completed with the help of Kent Chan! Thanks so much Kent!
