"Raptiformica"

I know. I bent the rules a bit. My image doesn't meet Al's supplementary
explanation of "The Unseen" challenge. On the other hand, I figure I've
still met "The Unseen" requirement since the ant that cast this shadow is
nowhere to be seen. ;) In fact, this image looks a lot more menacing than
other images where the ant is visible. I took this with a Canon 180mm
f/3.5L Macro. I put the ant in a shiny white plastic container and used a
strong flash to get the shadow. The ant cooperated by standing up on its
forelegs.
