Okay - I saw a post somewhere that told of shining a greenie in a snowstorm....I did the same thing with rain tonight....friggin cool as hell....DAMN nice looking - and I didn't even bust out the WL Nexus ! Just one of the 50mw ones....incredible....you gotta try it ! The beam refracts off of every rain drop - I shot my time tunnel prototype outside, and it looked awesome too ! I think I am gonna try to build a galvo system to run some basic programming, and do some crude designs soon. I say crude, because an artist, I am not !
