(Nathan, I'll send you the 300dpi graphic file. You wanted something photocopiable, so there we are.)
Readers: the above design is subject to change, but the basic concept for it came to me pretty much in the form you see it above (not my face, though; that's a conceited addition). One danger is that the bootprint image might be accidentally or deliberately misread by the clueless and/or by cynics (not to mention clueless cynics) as implying that I'll be stamping out all religions. Your reactions are welcome.
