Remember the old trippy display of Windows Media Player? Well, these videos by Robert Hodgin of Flight 404 are like that but infinitely better.
I'm going to show you two of my favorites:
Magnetic Ink ("In an Instant" from The Flashbulb's album Red Extensions of Me)
Solar ("Warren" from The Flashbulb's album These Open Fields)
These videos were made with open-source software Processing, with audio from The Flashbulb - Thanks KM Alexander!
