A very cool video made by Ryan Cashman that features a piano player animated with a green laser and long exposure time, pretty sweet.
This is how Ryan Cashman made this masterpiece:
Animated light paintings of a little piano player performing. Filmed at night with the lovely I-5 and San Diego skyline in the background. I would like to thank everyone for the fantastic feedback I have received lately. To answer a few questions, I wrote the music and recorded it first. The frames were photographed with a Canon Rebel using 20-30 second exposure time. I used a small green LED keychain light to draw each frame. Once all the positions were photographed they were strung together and synchronized to the music in After Effects.
