My submission to js1k/2014
Features a raymarched sphere field and a polyphone softsynth with polyrhythmic patterns. Voices are modulated pulses.
This is the version which compresses down to 1019 bytes. It only runs on chrome however. The branch 'compatible' contains a version which runs on chrome/FF but is larger than 1024b due to the web audio api being very verbose.
I submitted this to the ++ compo.
