Among other reasons, it makes no sense in Asian circles.

Well, how about a picture of those "Asian Circles"?

Magnifying glass is good.

Gets the connotations away from magic and into detective work and science.

I like it, but it also has other meanings, as does most good sculpture.

Good ideas, all. I'm actually rather fond of Pigasus, primarily because it'd make a great looking chocolate. The Thinker might have too many details to try to convey by way of choco-goodness... though it would make a dandy substitute for chocolate easter bunnies. How could you *not* bite the head off first?
