The Moebius thingie sounds interesting. I just tried to make that out of a scarf, and it reminded me of something else. Of course lots of things remind people of something else--that's why they're symbols.

Seriously, I think it's a great symbol.
Ebbie, I'm with you on the dragonfly--I LOVE them.
Becca, I love the tattoo. I remember it because when I saw it, I was wearing earrings that had a similar triangular-shaped Celtic knot.
