GBC - The River of Balls

Do you love GBC (Great Ball Contraption)? There are many sophisticated mechanisms which in various ways carry the balls. Most of them are bare modules focusing on mechanical issues.

This set is the mini GBC loop with theme - old man who fishes at the river near the waterfall. Water is composed of garage door elements.The river features a simple mechanism that gives the impression that the water really flows. Waves are created by the conveyor installed under the river.
