Hi all
I'm a newbie to Arduino and electronics in general, and this was my first Arduino project. I just finished it today, and I think it's turned out great for a first! I'm a huge fan of all things laser, and I figured that I'd like to try a programmable laser scanner build myself, and the ArduLASER is the result.
It's a 2D laser "projector" that'll make nifty beams, sweeps, tunnels and stuff like that in the air (a little smoke from a fog-machine makes it even cooler).
There's much more info and some videos and pictures on my blog and wiki. The source-code and some build info is available on the wiki as well.

Huge thanks to everyone from these forums that helped me in learning and building this! I am stoked that my programming skills can suddenly be used to build something "real" and not just virtual stuff ;D
