What else can I do with a laser besides burning stuff?
(I will keep it simple, I'm just giving some youtube links because I'm not capacitated to explain how these things work or how to correctly DIY them, well, at least everything but the spirograph hehe)

Time Tunnel: http://www.youtube.com/watch?v=28D73Sx1jFs
And more!
Are there white lasers?
Yes, they are lasers composed by RGB (Red, Green & Blue) colours...blah blah this is not my strength so I can't really help with this one (I would write about them but it wouldn't be 100% correct, I'm just giving ideas).
