Hello. So the other day I decided to make a basic Spirograph using a piece of mirror glued to a computer fan. And now that I've repaired my camera tripod, I decided to take some pictures of the "cone of light".

I rather like this. As it happens I have a little computer graphics card heatsink fan wired to a 9 volt battery sitting across from me... and a tiny little mirror I extracted from a PS2 laser. Could have a bit of fun with it.

The red light is a nighttime heat lamp for my lizard. I do believe it emits 650 nm light as the primary wavelength.
