Technique: A windshield wiper mounted webcam is processed by a laptop, creating a time lapse where the exposures overlap (no movement is lost). The audio comes from pitch-shifting recordings from a large solenoid (modified bass speaker) which were capturing most low-frequency vibrations (the higher-pitched sounds are music playing in the car).

Highlights: circles around star park at 0:34, motorcyclist trying to show off at 1:21, passing at 1:49.

Notes: The original length was about 26 minutes. There is a cut near the beginning due to some corrupted video, but it's hard to see. My sister Kiera McDonald drove, chose the path and music.
