Sculpt snow or do not sculpt snow, there is no try. That has to be the philosophy behind creating a snow sculpture this amazingly intricate. This great creation was made for the 2005 Sapporo Snow Festival.
Of course, that's not the only geek snow sculpture out there and you don't have to go to Japan to see something of this caliber. i09 has a great list of geeky snowmen and sculptures and these two are only the tip of the iceberg (or snow pile in this case).
