snow graffiti?

I've been slow in the starting blocks with my first post of 2010, I'm still kinda feeling stuck in the holidays - and also a little bored with the commercial work I've been seeing, so i thought - why not go with it and look into something wintery?With that in mind i started thinking about reverse graffiti and wondering if any of these great street artists take advantage of their frozen surroundings to create some temporary snow or ice graffiti. Though i didnt find the snow masterpieces i was secretly hoping existed i did find some evidence of snow graffiti...anyone have any evidence of snow graffiti? please send it my way!
