Maybe, I'm just throwing out ideas here, put a little word bubble with a question mark near it. you know, like it's questioning what you're doing? heh...or not. :P
i was thinking about it... wrapping it around... and it's funny you mention the "what you're doing" question, because there's a little phrase i say alot: "washyadoin? "
thanks for your input, i'll have another version up soon :)
it looks good on any color shirt, but these were my favorite.
