invisible lights

Immaterials: Light painting WiFi from Timo.

A four meter high rod studded with 80 LEDs was used to create light-paintings that present a long-exposure, line-graph cross section of the strength of the various wifi networks available in downtown Oslo. The invisible made visible, but not quite. Fascinating stuff. More on the process, as well as past projects, here and here. Also: the resultant photo-set.
