Clockwork generates the slow release of energy over time. In a clock, a series of measured events are fed by the mainspring - ticking, chiming, the slow sweep of the hands. In Cosmojetz, the spring drives an eccentric flywheel, and the whole rig shudders and bounces in a spastic frenzy on its eight spidery wire legs. It's another infectious toy like this one, by Brazilian mad genius Chico Bricalho and built by Kikkerland. It's a reminder of the giddy joy of analog toys.
