Had RGB already but my blue laser died early :-(
Scanners are Raytrack 35+ (jmlaser.com).
PowerShot A720IS, SanDisk Extreme III SD 2GB

I made it in absolutely dark room.  Exposure time 15s and strong flashlight. When camera flashed (what had not take long) i light up small flashlight in my hand and make light trail. So whole picture was made when short flash from camera occured and then nothing else can get into picture (i.e. my movements) except another light :) I was so excited discovering this technique than i cannot sleep to 3.00 am :P

very very cewl effect.and nicely figured out!!!!lol.
it proberbly could have been done nicer in photoshop,but the way u did it is way cooler.
good work.
u  do look a bit obsessed...lol
Al this lightpainting could be done by far better in photoshop than in reality.
Thats the name of the technique you invented.

Ok so I cheated a bit, these photos are over a year old and shot with EOS 30D. I just thought they'd fit in this thread.

I use a color-changing led from a decoration candle. The led sits on a small circuit board attached to a 9V battery and stroboscopically switches between R, B and G colors (look closely at the light paths to see it). I put it hanging from the ceiling and let it circulate with the shutter open. The first picture is done by putting the lens cap on and swinging the led a bit more (and repeating once more).

It's just a 65" exposure in nighttime, with me walking and waving a LED in front of the camera
