WTB: Polygon mirror or single axis galvo

Hi!

I'm building a DIY spirograph using red and green lasers, see thread here.

I'm looking for a polygon mirror for making a line or liquid sky effect. Perhaps a hexagon mirror with about 1" square sides would be suitable? Must be possible to mount on a motor.

Alternatively, I could go for a single axis galvo. I would need the galvonometer with a driver which I can feed a signal to, I would feed it with a sinewave to make it sweep back and forth.

Must be shipped to the Philippines.
