Does it ever bother you when you see a logo featuring three gears that are supposed to work together …because you know that won’t work? But you can get three gears to work together, if you build them outside the two-dimensional plane. Mathematician and 3D printer Henry Segerman shows us how to do it, with several different shapes. The Oskar Van Deventer ramps up the idea.
These contraptions don’t make the 2D logos any less bothersome, but it’s pretty neat. (via Metafilter)
