As there were some requests for source code for this light painting/POV stuff: http://coto.homenet.org/povtest.tgz
My original work was in a big testbed with lots of obsolete, alpha and beta stuff. Now I made a stripped down version with just this and added lots of comments. If there are still questions: just ask me!
All pictures shot with 10 seconds exposure time, aperture automatically choosen by camera. Unfortunately it’s raining since two days and I can’t shoot pictures outside…
Have fun and show pics!
