Cool Snowfall and Lasers

As most of you probably noticed, there is a large snowfall over almost whole Europe. I find the flickering of a laser during snow/rainfall pretty interesting. I decided to take some beamshots, both are with a 50mW 532nm DX SDLaser. One is 0.7 seconds and the other is 1.5 seconds. My camera decided to die afterwards, so after I will get my batteries charged again, I will post some longer exposures.

Does anyone have something similar?
