Music Visualiztion Custom Application

Create custom software application which will convert ratios in MIDI data, to visual patterns. Vice Versa , output MIDI from ratios in visual patterns drawn in photoshop or a similar program. This is meant to be run as a VST or AU plugin for music production and graphic design. It should work in real time. A Java Applet or Flash is also acceptable. I have the algorhytm, I need you to dress it up in code. The progarmmer must be able to sign a non-disclosure agreement.
