Via @GreatDismal, comes now this interesting QRCode project – Graffyard. I’ll let the artist give you the run-down:
I am using QR Codes to preserve graffiti for posterity by photographing the graffiti before it is removed. After the graffiti has been cleaned off by the local authorities or building owner i place a QR Code in the exact location which resolves to an image of the original. In that way a mobile phone with a QR-Code Reader can be used to travel back in time.
Reminds me of a similar project – one to embed QRCodes that link to street art. Where did I see that…? >grin< One interesting enhancement that occurs to me – the ability to page through various versions of the surface in question – a time-stream of modifications/tags/etc.
@Spyboycomments, “But the QR code IS graffiti too then. An augmented reality app that overlays the graffiti on the clean surface would better.” First and foremost – agreed. A couple of caveats though:
The QRCode approach is do-able. No RFID xmitter/receiver needed, no GPS fix required, no AR app installed. Point your phone at the meta-graffiti and away you go. It’s important to keep in mind that we in the US are way behind in cell phone kulturny – QRCode readers are almost a given in Japan and very common in Europe.
I like the idea of a human-detectable (if – obviously- not human-readable) cue. The code is an indicator – ‘something is/was here’.
The ‘AR app on a clean surface’ gets me thinking – will the next gen tag battles be waged by folks with good tech chops trying to subvert each other’s AR data?
Having come up with a viable (meltybeads!) tiling scheme, it’s time to officially launch! If anyone wants to deploy a mediated toynbee tile in their neighborhood, fantastic. If you’d let me know, with a picture and a location, even better. My tile dropping will have to wait on warmer weather but you can expect daffodils and QRCodes to bloom simultaneously up here.
OK, now I’m really dangerous! Twelve thousand melty beads in the mail today; 6k white, 6k black. I need to figure out a bombproof container – picking them out of the rug (or worse yet, having the dogs pick them out) is not my idea of fun.
The abridged version of what the project is all about: QR code tiles that lead you to a page with random pictures of Toynbee tiles. For a more complete explanation, click here (or on About above or in the right margin). I’m hoping that someone may decide to install a mediated toynbee QR code tile in their neck of the woods…
As you can see from the post below, I’ve been experimenting with Perler (aka melty) beads. The starter kit I bought didn’t have enough black and white beads to finish the QRCode and I didn’t want to buy any bulk bags until I’d proven the concept so everything waited until today, when I swung by the local craft store and bought a mixed refill bag. Voila!
A big thank you to Eric fritterfae Riley – steps 3 and 4 of his cross stitch Instructable really simplified bead layout. And the test run:
I don’t think my cell phone camera/scanner SW copes well with low-light conditions – it wouldn’t scan in late afternoon ambient light and I had trouble scanning a QRCode in a movie theater lobby (dim) recently. At least, I hope that’s why scanning was temperamental; more testing wll be done tomorrow.
And the explanation for the post title (for those of you who haven’t seen other references to it on the blog) is here.
A little self-referential, what with scanning the QR Code from the blog rather than from a tile on the street – so shoot me. In any case, here’s the sequence – 1) scan QR Code, 2) go to scanned URL, 3) see a Toynbee tile.
Summer weather continues to avoid New England – yesterday and today are the first consecutive sunny days since May. The epoxy and the ‘clamped’ (parked truck w/ one wheel on the tile) Gorilla Glue are still in the running.
