If I go to a robotics event where CDers are likely to be, I wear a nametag. It has the stuff on the left side of my profile (avatar, WAI, name, that sort of stuff) and orange-and-black bars to bracket it and make it look nice. I put it in a plastic clip-on nametag of the sort you'd get at any trade show or something of that nature, then clip to my shirt.

Edit: the attached picture, which is an example of what I do, was done in about 5 minutes just by doing a printscreen (from this thread, no less!), cropping, and adding a pair of bars on top and bottom in Publisher, then grouping and saving. It would, of course, be clearer when in a nametag.
