Has anyone done this with Pd? I thought I remembered something in GEM, but I can't find it anywhere. Just to have a cursor scroll left to right and assign the different values of pixels to different musical properties...

Like this?
Yeah, I think so. How's it work? Thanks for sharing.

Not sure exactly, it's not my patch, but from the screenshot it looks like it copies a scanline of greyscale pixels into an array, then rescales the array exponentially into annother array (frequency<->pitch conversion), then does an inverse fft and sends the resulting audio to dac~; the partials of the output sound being determined by the particular scanline of the image that was just copied to the array.
I think this technique is a form of "scanned synthesis", but I'm not an expert on terminology. At least searching pd-list for that term shows up some interesting results...
