EXPLORATORIUM CLOCK

 

..

The roof wasn't high enough to put the gong on top

The clock has 12 mechanisms round the base connected to plywood 'tinkerers' up the tower, working on the numbers. Visitors can operate individual mechanisms and tinkerers by turning knobs which project through the glass enclosed base.

On the hour, the numbers light up and all the figures and mechanisms are driven by motors. The numbers then swing out to form a dial and the gong at the top strikes.  The numbers then return, wrapped around the column again.
