Japanese woodworker Kazuaki Harada (previously) has spent the last few years designing these playful automata that activate with a simple hand-crank. Watch miners work in tandem, a figure cackle with unparalleled enthusiasm, and the devil aggressively play the fiddle, and make sure to turn your volume up, too—Harada often pairs an audio component with the mechanical movements for an additional dose of whimsy. For more of his quirky designs, which include many of the character-based works shown here in addition to more elaborate, abstract pieces, check out his Instagram and YouTube.
