A 3d printed zeotrope (or Four-mation) of ghosts and pumpkins. Shared by Mike Rigsby on Hackaday.io:
After all the “flashing bars” don’t seem in actual life. An Arduino with a motor defend is used to regulate a bipolar stepper motor and led gentle strings. The twelve inch diameter turntable rotates at about 60 rpm (one revolution per second). The turntable is split into 20 sections and a ghost/pumpkin is positioned on every part. The led’s are “flashed” each 1/20 of a second to supply the phantasm of motion.
