Part of a series of explorations based on audio and geometry. In Houdini the audio is generated from 3D geometry. As the particles collide they create an audio pulse based on their height. The is also audio generated from the small burst of particles. The outer and inner ring also emit a constant tone. The Plexus like effect also generates audio based on it's height. You'll notice it pop in and out based on the proximity of the points.
The basic elements are exported from Houdini into Cinema 4D where cloners and splines are used to create additional geometry for render. I then finished with a simple composite and mix in After Effects and Audition.
