I've also used Playing Card Dominoes in the past for seating tourneys... lay out the Ace-9 of Spades and Ace-9 of Hearts (or whatever) all upside down, and people pick a dominoe for their seat/table. Ace is seat one and starting dealer, and gets to pick their chair.

Amazon used to have them at a much better price, but they appear to be
out of stock.
