There’s something hypnotically satisfying about drawing the endless circular patterns with a Spirograph machine—unless you’re hopelessly lazy. Then it’s just another form of work you’re trying to avoid, and you’ll probably love PG52’s latest creation. It’s an autonomous Lego Spirograph machine powered by a single motor connected to an impressive four-speed gearbox. Its engineering is as much a piece of art as the spiral patterns it sketches.
