This is very cool.

I would be interested in collaborating with you to add some more physics: refraction (laser passing through slabs of glass) and curved surfaces (parabolic mirrors and lenses using the thin-lens approximation).

This would be the coolest way to learn about ray-optics.

Nice ideas! I have a small list of higher priority features to add first, but I am adding these to my queue:

- refraction polygons - concave/convex lenses - concave/convex mirrors

I think the easiest way to add these would be to just make them fixed objects in the level (so the only drag-able items would still be the straight mirrors).
