In the past few years, we have covered plenty of amazing clocks here. This Steampunk Gear Clock is also worth a look. It is a 7′ kinetic sculpture carved out of 30 and 80lb high density urethane foam board and steel. It has RGB color changing LED lights and moving gears.
This clock is quite hefty, coming at 300lbs. The makers have gone out of their way to give it that rustic, Victorian look. You can find out more about it here.
