Penrose Gears are a serendipitous spin-off of Oskar's Star Gears (https://www.youtube.com/watch?v=EvVSUPFSYN8). Playing with the pentagonal star gears in CAD, it became apparent that an aperiodic surface-filling grid was possible with these gears. It is yet unknown what this grid would look like at a larger scale. There a three types of gears: blue, yellow and red. Although physically identical, each of these has a different role. If all the yellow gears would be turned at a constant rate, then all red gears would accelerate and decelerate simultaneously and dito for the blue gears, but when red accelerates, then blue decelerates.
