Hi!
Just some days ago, Sonic Charge released JS80TRX as a fun project. It is a browser based chiptune tracker with three voices and eight patterns. All for the joys of limitation All songs can be shared easily, since the tune itself can be encoded into the URL.
When I heard about it yesterday I immediately created a little tune, inside the Safari browser on my iPhone.
