Ball and Ramp is a paper-based rolling ball sculpture toy. The system made up of various parts. Each part has a particular function, and together you can build a rolling ball track.
Use tape, push-pins, glue, magnets, or anything else you can think of to attach these parts to your walls, fridge, doors, or anywhere you want an interactive sculpture.
These parts may be made of paper, but they’re pretty durable. If one of your parts gets crumpled, you can just iron it out, and it is usually as good as new.
Rolling ball sculpture is an established art form with many practitioners still creating new forms. You might want to read the Wikipedia article on RBS for more info.
