Image-based music synthesiser

Imagine Brainloller, except instead of outputting characters and maybe doing a sum or two, it outputs noises and controls the attributes of a set number of oscillators. Perhaps different RGB values correspond to different operations and methods; consider logic-based control structures, complex polyphonic multiple-oscillator multiplicative synthesis combined with ENTERPRISE-LEVKidding. and waveform modifiability to boot.

I haven't read SICP in the last couple of days, and I just thought of this about 20 seconds prior to starting this post.

Why, though? Do you have a rationale?
