Ooh! That looks like fun! That's Jake Bronstein of Zoomdoggle playing around with the Laser Finger Beams. You can even make your own "light sculpture" photo by using the Shutter-lag setting on your camera: Link - Thanks Kristina Hoge!
Once you get the hold of that, try making this one: Lightmark
What a retard, hope his head explodes from eating X.
I'm definitely going to buy a pack when I get money.

They're not really lasers, as they advertised. These are actually 5mm LEDs powered by 3 AG3 button cells each. You could use these to make $0.38 LED Throwies (plus magnets).
NB: Do not shine directly in eyes.
