Artist Andrew Frueh describes his papercraft
Ball & Ramp system as a "folded-paper rolling ball sculpture toy". Rolling ball sculptures are a form of kinetic art that make use of gravity to roll small balls through a series of ramps and other contraptions. Frueh's glue-less system makes use of three basic components: a ramp, a cone, and a basket. Free PDF templates for the components may be downloaded from the
Ball & Ramp website. As
Ball & Ramp is an open-source toy, it will be exciting to see how the toy grows and evolves with input from creative people around the world.
