A new art/media/tech project has emerged which combines a handful of some very diverse elements. Part street art, part real-world websurfing, part tagging. Yellow Arrow brings online features to the real world.
Basically how it works is when you see an arrow out in the world (you can order the stickers on their website) you text the code with your mobile, or go online, and you will get a response that provides a description of what the arrow is pointing at. It's difficult to describe but a very cool merging of mobile, street, and human communication. The video is a bit over the top but it explains all.
This harkens back to Space Invaders, which dabbled in the participatory nature of street art. But it opens it up and allows others to comment on the same arrow. I guess in that way it's a little like geochaching.
At any rate, I'm curious to try it out. Have you?
