if you've been to stockroom you've no doubt crossed paths with the work of the rather wonderful cameron robbins. his swirling water vortex and his smoke vortex at the back of the building are without doubt the most asked about pieces in the building. there's some gorgeous drawings of his too that are quite something to behold.
