Just recently finished this working LEGO ball maze, also commonly known as a Labyrinth. It features a removable ball storage container, travel lock and interchangeable mazes.
I built three mazes for it, including a space themed one and medieval themed one.
I also put together a video showing how it works.
And for those into CUUSOO, you can check out the project there.
