Who you calling a square?
These little guys are subtle puppies. You might have to click to enlarge this picture for a good glimpse of the quarry.
Much the same except they're crawling up the side of the door rather than scuttling along the bottom. (Go Air America!)
I like this square-within-a-square motif. Bold, and yet...
You might do a double-take and take this for a star at first, but of course it's "four-square."
No mistaking this one -- solid, Jack!
