Geared Whiplash - manual version

More OskarPuzzle at Geared Whiplash is a Yo-Yo-type gearing contraption with no obvious use other than tactile amusement. It is a snake of gears, in which each segment drives the next segment. The shape can be curled up quite compactly. It gradually unrolls and when it is nearly fully unrolled, it sweeps around like the end of a whip, hence the name “Geared Whiplash“. After the whipping, the contraption rolls up again and the sequence repeats. Copyright (c) 2016, M
