Get a copy going for the buffer example
	When it arrives:  Buffers, staging memory, follow the pictures in

I've thought about it and decided lab should be on project 2
	Since presentations start next week
	We'll do another RTX lab next week

How about something that's reflective?
	There's a demo of that, so let's have a look
	Two walls normally, but we could always put some other stuff in this
	Number of reflections:  We should be able to set a limiit
	Loop in shader?  Probably a bit hard on performance
		Can we check?  Shouldn't be too hard, might have to adjust sizes

How does the demo know what should be reflective?
	Material files
	So we should be able to make other stuff reflective too!

How about a convex mirror?
	Like, a sphere or torus or something?
	Normal vectors and reflection
		I don't see why this won't work
		Might be limited in creativity...
	How about a reflective torus?
		Perhaps with some other things around it
