Dali’s Ovocipede (Apr, 1960)
Looking like something dreamed up by Salvador Dali (it was), the ovocipede is a transparent plastic sphere that is propelled by the occupant, who runs along on the inside track like a squirrel in an old-fashioned squirrel wheel. The famous painter claims that the “vehicle” can be rolled over land, water, ice, or snowâ€”the operator stands and holds the two hand bars on the axis, or can sit on the seat to coast. Steering is managed by shifting the weight along the axis in the direction of the turn. The driver turns around to reverse.
