Default How would I create geometric shape from...

An array of lasers and mirrors? The idea is to create a pyramid under 3ft tall with a series of mirrors for a halloween party. I've owned several hand held red lasers, but never anything more powerful than 5mW and I've always wanted a green one, so that's what I'll buy this time. What I'd like to know is what has the best combination of luminosity and price/performance considering the application that I'm attempting.


Thanks

A 3 dimensional pyramid would technically, be very difficult to produce. It would require a combination of beam splitters , and mirrors alligned very precisely as well as a fairly high powered laser, considering the losses encountered with the beam splitters. A better bet would be to produce a triangle that could rotate about a single axis, using a simple 2 motor and 2 mirror system.

Me and Merl made one on our recent get together.
