This clock was made from a chunk of cholla root I found in a wash after monsoon. Polished by the sun and wind and rains in the desert, it had a very sculptural feel to it.
The base was a wood base most likely from an old lamp. The lid to an old oil can (remember those?) fit over the base.
It took a little bit of work with the Dremel to hollow out the back so that the clock works would fit. The only finish is a few coats of linseed oil to keep the wood fresh.
