That looks rad. I'll have to try it out.

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...

So, it seems to me the input would have to be a couple of pixels at a time, with a small block size, in order to scroll. Like enter a column of pixels and do, as someone mentioned, reverse FFT to get a block. Maybe map the image to a rectangle with width 1, then slide it across? I don't necessarily have to see the scrolling or even the image, but it would be nice. I don't want to be obnoxious, but I know next to nothing about Gem, so any suggestions are welcome.

Here's what I have so far, using: http://upload.wikimedia.org/wikipedia/en/d/df/US_%241_obverse.jpg Since it's not copyrighted. I don't understand exactly what's happening. It doesn't sound to me like it's what I want; the frequencies just don't seem to line up.
