There’s been a load of light-animation both in the independent film industry and in advertising.

This clip by Ryan Cashman takes the technique a step further by letting a funny character animation of a little green creature playing the piano.

How did Cashman create this video?
Animated light paintings of a little piano player performing. Filmed at night with the lovely I-5 and San Diego skyline in the background.

He wrote the music and recorded it first. The frames were photographed with a Canon Rebel using 20-30 second exposure time. A small green LED keychain light was used to draw each frame. Then all the positions were strung together and synchronized to the music.
