Evolution kinetic sculpture full cycle video

This video shows one full cycle of the kinetic wall sculpture entitled Evolution. Full cycle is the time from one push of the spring mechanism until the next. Evolution has a particularly long cycle time of about 5 minutes. Initially the two wheels move in opposite directions at similar speeds. The back wheel usually (but not always) slows down first and starts rocking back and forth creating constantly shifting patterns throughout the cycle. I find some of the most interesting patterns are created near the end of the cycle when both wheels are moving very slowly. Total run time is about 4 hours per complete winding. You can find more information about Evolution by going to the Evolution page at woodthatworks.com. I've detailed my thoughts throughout the design process earlier in this blog starting here.
