This is very cool. The core of the code should be pretty simple, here's an article on how to play an image using windowed fft : http://www.ohmpie.com/imageencode/ Then just add some standard chorus+reverb processing, possibly a bit of distortion. There are other programs that do this kind of thing (Photosounder, MetaSynth), oddly not so much free software. As a side note, it's kind of odd that the coloring in this gui lays out the light spectrum with the low frequencies in violet and the high frequencies in red. |

The Analysis & Resynthesis Sound Spectrograph is the closest thing I can think of: http://arss.sourceforge.net It hasn't been updated in a long time but it's still very useful!
Michael Klingbeil's SPEAR is also open source, but a slightly different beast - focused on manipulation of analysis data as a set of partials - it's still insanely useful: http://www.klingbeil.com/spear/
Chris Penrose's excellent Hyperupic was the first tool of this kind I remember encountering, inspired by Xenakis' UPIC system: http://music.columbia.edu/cmc/MusicAndComputers/chapter5/05_... It died with OS9 to the best of my knowledge.
EDIT: Just to say that Alexander Zolotov's work is blowing me away. I didn't realize he was behind SunVox until now, but the portfolio of his projects in this thread is really inspiring.
