Joe Hoffman made this clock in the shape of a single coil stratocaster pickup . Six nixie vacuum tubes display the time, where the pickup's magnets would be.
The top and bottom of the pickup-clock were cut out of stainless steel by the Big Blue Saw Company. You send them a design and they will cut it out using their CNC waterjet and send it back to you.
