She
Looking around vorc, I found she. Seems like she's a japanese girl doing some experimental-ambient-chiptune music (she does the chiptunes with two gameboys at the same time and a very popular gameboy tracker, the Little Sound DJ). Listen to the songs in the music section, they are quite fresh and interesting.
Maybe I should contact her for getting some music for a ppg-like demo!! ;)
UPDATE: I discovered she is in fact he.
