Spin the phenakistiscope to see how old-timey animation works or try making your own with the chalkboard version.
Phenakisitiscopes were the first widespread animation machines that gave the illusion of fluent motion (like we see in film). They originated in the early 1800s.
This version is built using upcycled bicycle parts and wood disks left over from spools of rope used in manufacturing. Some of the disks feature images from Eadweard Muybridge, a photographer who studied motion in the late 1800s.
