Inspired by my favorite artist Arthur Ganson's "Machine with Concrete", see: http://blog.makezine.com/2012/04/25/arthur-gansons-machine-with-concrete
This is a printable version of Machine with Concrete. The sculpture is a series of twelve 50:1 worm gears, with each gear reducing 1/50th of the previous gear. With 12 gears, the final gear ratio is a mind boggling 244,140,625,000,000,000,000 : 1 (244.14 quintillion to 1). With the first gear spinning at 200RPM it would take over 2 TRILLION years for a single revolution at the end of the machine, so the final drive shaft can be embedded in concrete or plaster.
I emailed Arthur Ganson a link to this page and he replied "looks FANTASTIC!". For a great introduction to Arthur Ganson and his work please see: http://www.ted.com/talks/arthur_ganson_makes_moving_sculpture.html
