Out of This World Cooking: a chance for a limited group to participate in preparing some exotic dishes, under the direction of Mia Sherman (in a suitable other world outfit), that can be microwaved into being and sampled (perhaps judged). There was a suggestion that this booth could also feature a PARSEC cookbook, if we could collect enough strange recipes.
Picture yourself as an alien on an alien world - and get a copy of the picture to take home; using a digital camera, a computer and a printer, wizard Henry (Tjernlund) can do this!
Buy a slave at the auction, or volunteer to be one. (OK, this doubles as the costume contest, with audience voting on the costume by bidding or something).
Eat and drink at Quark's - the lounge where things regularly Happen. Not only does your drink look strange, but you can participate in interworld quarrels, help catch alien criminals, take bets from Quark, and help stamp out tribbles.
(ok, you're really part of an improv theatre group, with staged - but not always announced - events).
Add your own announcement to the background announcements: if we like it, we'll read it. And if you make up an outrageous commerical, as bad as Bill Hall's, we'll read that too.
Join a Tour of the galactic midway, if you're uncertain of what to do next. We'll guarantee that it will be - different.
Join the PsiCorps - or at least fill out the application, which is of course, not on so mundane a thing as paper.
Find out who is the Alien - take a test to prove your Humanity (or not).
Learn to speak a few phrases in an alien tongue (eg Klingon); these may come in useful later in Quark's, when bribing the cop who wants to arrest you.
