The system is built in a partial icosahedron (no bottom vertex, so
it sits like a geodesic dome), with speakers at each vertex, one
directly overhead, five in a ring part way up, five in a ring at the
bottom.
Custom software controls the placement and motion of sound, and allows
for songs to be composed, in up to 8 channels, with the location of

I wrote retellings of a small set of star and constellation myths,
mainly concentrating on Greek mythology, but with occasional forays
into Hindu, Native American, and southern African myths. I rounded up
friends to do the voiceover readings for the stories, and then wrote a
software module that will do the star math to figure out where the
constellation is in the sky at a particular latitude and longitude,
and then play the story from there.
