This entire project could have been done as an app, drawing the maze and ball virtually on the screen. But that wouldn’t have been nearly as fun as what [Matt] accomplished. He built a little Labyrinth which responds to the accelerometer in his phone.

Take a close look at that handset. It’s not an Android, an iPhone, or a Blackberry. That thing is a Windows phone…. no, really! The phone doubles as a timer, which we think is a nice touch. It communicates with a Netduino which is both driving and monitoring the Labyrinth.

You may have noticed that the maze is hand-built rather than a modified commercial version of the toy. He mounted some hardboard on a pair of servo motors, then built up the maze on that surface.

We’ve embedded the demo video after the break.
