Rebecca’s Outfit is a running accessory designed to motivate the runner to keep a fast pace by subjecting him/her to horrendous music. Rebecca’s Outfit will play a song on the annoyance level of Rebecca Black’s “Friday”; if the runner is running fast, the song will play faster than the normal playback rate, and if the runner is standing still, the song will play slower than the normal playback rate. If the runner wants the song to be over more quickly (and also sound more hilarious) he/she will surely be motivated to keep running at a fast pace.

An additional component is a pair of sunglasses with a row of LEDs on top. The LEDs will blink with increasing frequency as the runner’s speed increases.

This is accomplished by an Arduino with a Wave Shield to play music, and an accelerometer to calculate the speed of the runner.
