If you were at Maker Faire Austin, you may have seen this honky-tonky belt buckle Ryan from SparkFun built which incorporates an MP3 player. It even has an MMA7260 Triple Axis Accelerometer on it to create a hip-thruster interface (i.e. you change songs by thrusting your hips). Oh, THAT’s not going to look embarrassing on the subway. But then, the entire buckle is dripping with sartorial wrong sauce.
