Hello
I'd like to make a piece of wall art involving lasers and smoke.
To begin, take a poster-sized glass enclosure and put it on the wall. It would probably come off the wall about 2 inches, so we'll say a 36x24x2 glass enclosure. Next, pump in some smoke via tube and fog machine.
Below the case of smoke, also on the wall, is a green laser in a fixed position, pointing down at a small mirror (say 3" x 1"). This mirror will reflect the laser beam up (parallel to the wall) into the glass enclosure. In order to achieve the desired effect, the mirror will have to be motorized somehow to rock back and forth very quickly to illuminate a cross-section of the smoke.

Here is a simple picture of the setup:
So how should I power that small mirror? Or is there a better way of doing this? I have limited knowledge of DC motors, but I do know that there would have to be some tricky mechanics to making it rock something back and forth, instead of in a circle. Someone mentioned that I should research how buzzers work (electromagnets and such), but I'm hoping someone here could get me started on the right track.
I really want to get this working! Please help!
THANKS!
