The Chaos Machine is a massive collection of tubes, tracks, motors and other widgets that can be used to move marbles around a layout that you build yourself. It’s a bit like Lego, only with marbles racing around. The main components of the machine are produced in kits from Chaos Toy. What makes it chaotic is that anyone and everyone is encouraged to change the machine while it’s in action.
This site is devoted to cataloging information about the pieces that can be put together to form a Chaos Machine.
