Opposite Earth by Jeff Snyder.
If you want to try out controlling the piece yourself, visit https://spiricom.github.io/sunspots/planets/
To use that website, it requires Chrome with experimental canvas features enabled in chrome://flags
It's controlled with the computer keyboard and the mouse position:
` (the top left key below escape) selects all rings.
numbers 1 through 8 select individual rings.
9 makes rings visible or invisible.
0 adds or removes moons.
- adds or removes ticks.
p adds or removes planets.
the arrow keys add or remove the "play" lines.
s, d, f, g, and h set the color of the next line you add (and therefore the scale).
z through / set the division of the ticks.
mouse X position is the size of planets - maps to decay time of notes.
mouse Y position is the blue/red color at the upper left hand corner of the screen. It maps to timbre, dark to bright.

We don't have a recording yet of an acoustic performance. Here's a rough iPhone video of a performance at the Princeton University Art Museum.
