Andy Goldsworthy creates art out of just about anything in nature, including snow.
Adam Rifkin stashed this in Art!
He built this over a pile of rocks, which he used as a support. He pissed on the rocks, and they froze together overnight. Took him four attempts to dislodge the rocks.
Spiral made out of icicles and spit.
Iceball under construction. Artist for scale.
