Light painting, a brilliant technique

Absolutely brilliant. And light painting has many obvious extensions and uses.

It might be called "light mapping" (which emphasizes the quantitative measurements depicted by the light stick and recorded by the fixed camera) rather than "light painting" (which suggests painting as in brushes and art).

All done with a still camera on a tripod and a person carrying a light stick with a measurement instrument attached. Video by Timo Arnall, Jorn Knutsen and Einar Sneve Martinussen:

Another Norwegian contribution to analytical design!
