Ok, this one is the product of sheer boredom.  I started with a snapshot of a coyote pawprint in sand, and superimposed a metal model airplane I photographed at Restoration Hardware, thinking I might need such an image.

After Superimposing and masking, I applied Astral Glow somewhat sparingly. If you squint a little, it almost looks like a plane in flight over forbidding desert territory.
