Very nice!! (if you have a cheap red, you could REALLY show how much more visible your beam is in comparison next time it rains...)
I think it fairly accurately represents what the beam looks like in the rain - I haven't been able to capture this effect myself... What type of camera are you using?
Very nice effects... We get a lot of storms here and I always end up standing outside with all my lasers looking at the speckle they make when hit by rain... it's like huge refractive dust falling all over the place! lol ;D You have captured it rather very nicely though
