“This machine was inspired by dreaming about gear ratios and considering the unexpected implications of exponential powers.” – from YT video

A kinetic sculpture of connected gears called “Machine with Concrete.” The 1st gear turns at 200 rpm and the last gear is stuck in concrete. It can still run because each gear set reduces the turning speed, meaning that the last gear only revolves every 2 trillion years.
