The Apple II popularized many processors and chips, most notably the 6502 . But as a games  machine, the Apple II relied heavily on an unsung hero: the 555, a timer IC that allowed two joysticks to be connected for head-to-head play.
Now you can give the 555 a new lease in your daily life courtesy Mad Scientist, which has adapted the chip into a footstoo l.
According to their blog, all it took was "datasheets, cnc routing, laser engraving, plywood, glue, chips, all-thread, angle grinders, mountains of sawdust, dowel rods, [and] spray paint." Sadly, none of those ingredients allow the footstool to interface with your Apple II. Nonetheless, this retrofurniture can be yours  for the exacting price of $555.
