David has constructed a huge circular ball maze that is 1.2m in diameter, as a contribution to a school's "Creative Games" section. And it is certainly creative, taking what is normally a pocket-sized game and bringing it to life. It can either be controlled using an Android phone that has an accelerometer, or a wired controller. For example:
With some neat woodwork and construction skills, this project can become a reality for anyone with the inclination and time. To get started with this project or Arduino in general, a good start would be with our Freetronics Eleven - the Arduino-Uno compatible with onboard prototyping space:
