Animation for Kepler's Music of the Spheres

The performance, lasting about two minutes, comprises a quadraphonic sound composition by Paul Viotti, and an animation by Ralph Abraham. These will be played in coordination from a computer program, with four speakers and one video projector.

In this website we explain the animation.

And here are some (silent) animations (2 minutes long). The colored disks represent the planets passing a narrow (30 degrees) window, seen from the sun. From the top down: Mercury, Venus, Earth, Mars, Jupiter, and Saturn.
