Another idea would be to use a hard drive actuator. I've got a 20gig Maxtor
D740X here that has a dead motor... I wonder if the voicecoil actuator could
be modded to operate a mirror. An interesting idea, nontheless.

Now THAT would be cool, but I'd rather play Asteroids. Wonderful monochrome
vectors - much cheaper :)
If you wanted to do Star Wars, you'd probably need to rig up a DPSS green
laser and some form of blue laser to do it properly. With Asteroids you just
use a red laser pointer :)

Later.
