One of the recent project of Adam Somlai-Fisher, Usman Haque and Bengt Sjölén is " Wifi Camera Obscura":
Wifi Camera Obscura reveals the electromagnetic space of our devices and the shadows that we create within such spaces, in particular our wifi networks which are increasingly found in coffee shops, offices and homes throughout cities of the developed world. We will take realtime "photos" of wifi space.

Why do I blog this? not because it's made up of wasabi cans but rather because I find the idea of revealing the "the electromagnetic space of our devices": visualizing the info cloud is compelling to me; both in terms of tech awareness in the environment as well as for aesthetical issues.
