As with the previous image, I've forgotten where on the Internet I found these amazing images in the Aztec style. They aren't historical, but were done by a contemporary artist whose name I do not know.
But the way this two-headed serpent spreads across the image to block
any passage through or around them
reminded me at once of the Windows NT kernel, where the hapless developer often finds himself caught between two
unpleasant alternatives: to "deadlock" or "crash". If you try to be "too safe",
an i/o deadlock is often the result, but
if you play it "fast and loose" you're often just one small step from a system crash -- another BSOD coming at ya. That's what
immediately came to mind on seeing these marvelous figures. "Have
a nice day?" Fuggedaboudit!
