Jan van Nuenen’s Flowers is an interesting experimental electronic music video that explores the idea of using the Monome to control audio and video generation at the same time. 
Here’s how it works:
The home made Monome is connected to a max/msp patch called boiingg (great app for the monome).
Max sends midi to Ableton <ive, triggering some [...]

Another audio-generated landscape music video from Flight404.

Videos like this make me think we’re on the cusp of a new era of audio visual psychedelic media; this time, it’s going to be HD, interactive and real-time. 
 ”I made the following demo because I wanted an easy way to showcase what Processing can handle in real-time,” says creator Robert Hodgin. 
Details on how the video was [...]

Tokyo-based d.v.d is a trio with two drum players, Itoken and Jimanica and visualiser Takashi Yamaguchi (ymg) on the hardware front.
While the two drummers furiously beat two drum kits in front of a huge screen, their sounds trigger geometrical shapes with processing, Pong-style game settings or bizarre drop landscapes that interact, transform or collapse. 
Jimanica explains [...]

This if the final version of Glenn Marshall’s video Music Is Math.
It’s a generative video, and Marshall says “I just let the program run till the end of the music, I felt reluctant to interfere too much by trying to sculpt an ending, and just let the code run its own natural course.”
Nevertheless - it’s [...]

This video from Zonkout demonstrates a self-generating modular synthesizer (Blacet+Modcan) patch with camera-less video feedback, performed live.

This cool video, Sound Reactive Boids In A Flowsphere, by Rui Madeira, uses generative video software to create an abstract take on Aphex Twin:
audio reative visuals made in c++ using the amazing openframeworks library
Song -> aphex twin - 4
i used a perlin noise class which can be found here :

Robert Hodgin put together this stunning generative music video for Radiohead’s video contest, but realized that the result didn’t have that much to do with Radiohead.
It’s very cool, just the same.
