Clayton Boyer designs and builds unique custom clocks, such as the Nautilus above, and sells plans to over ten of them. Each clock is handmade almost entirely from wood, including the gears. He typically tries to inject some fun and personality into the clocks, as is apparent from his description of the Nautilus:
"This beautiful clock beats about 90 times a minute, and 'tinkles' the hour by lifting, and then dropping the curved, horizontal arm, thus causing the chimes to sound. I wanted to create a striking clock that didn't intrude upon ones conciousness, where the hourly strike is more of a happy afterthought."
More pictures, and plans for the DIYer types, are available at Clayton Boyer's Clocks.
