Checking out Gizmodo's coverage of the CES show today has this sweet LCD table (the Entertaible) that updates in real time for gaming. This would totally rock if you were into some hard core Dungeons and Dragons or something. I'm sure for a 30" LCD it's like a bajillion dollars though.
Even cooler than that however has to be the BatTV. If you actually owned the BatTV I think I would fly to wherever you are and kiss you on the mouth.
