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".

Ive done that too.
It gives great results with some steam and cold air.
 
what is the red light in the right side of last picture? is it red laser light looks bright
 
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.
