Hmm, that looks like a 2D galvo scanner. I was thinking more like a laser pointer and a mirror attached to a motor.

You just have to build it! It's definitely possible, and the only question I have is the power of laser needed to be visible in your environment for a given circle size, and a simulation will not tell you that.
