Designer's Journey
Rube Goldberg's mechanical comics inspired ROKR to design a future city in the industrial style with steel balls and multilevel tracks. With gear transmission and energy conversion, the steel balls can run smoothly without electric power. This creation serves as an educational tool for understanding marble runs and pays tribute to Rube Goldberg's mechanical storytelling.
