Pottering around I found this site.
linky
I already have a Class II <1mW red laser pointer that I use to wind the cat up and mess about with in the dark. But 450+ x the power and green well thats just got to be better anything else. The lower power ones (75mW) will pop ballons and cut plastic
Now if I just sell the car I can have one. (plus I'd need to convince claire)
Check out the vids
