PSK Visual CQ

After Rich KD6WYK told me he gets better responses to CQ when he sends a long idle tone first, I've been toying with using a Hellscreiber-like encoding of text in a PSK signal, as part of a prelude for doing CQ. I asked Erik Olson, author of baudline, about embedding images in DFTs, as I'd seen one somewhere before, and he told me the one I remembered was the aphex twin face, and also told me about Jason's work with color images using stereo channels (and Erik contributed a phase-angle idea for getting a third channel).
