Arduino-powered Labyrinth Game with Joystick control
If you're handy with electronics and woodworking, then this interesting project by Instructables user Kevr102 will be of interest. They have built a wooden Labyrinth style game, that involves a maze in which a ball is moved from the start to the end by tilting the base across the x- and y-axis.
However this unit has the tilting across both axes controlled by a joystick and two stepper motors, with the Arduino as the brains of the operation. You can see this in operation via the following video:
Certainly something different and an ideal use of the Arduino platform, which is great for rapid prototyping and embedding into projects such as this. For more information, visit the Instructables page.
