I took this directly from Keith Baker's open livejournal blog.  Looks like you've got about a week to get working on this:

It's been a busy month, compounded by a recent trip to the east coast. One of the things that has been keeping me busy is the Tower of Gygax - an event I'm coordinating at GenCon Indy 2008, one of many events honoring the memory of Gary Gygax. The goal is to have a continuous game of AD&D (first edition, the one with the efreet on the DMG and the jewel thieves on the PHB) running at GenCon - 80 hours straight.

The idea of the Tower is that it plucks rooms from many worlds - every world that Gygax's work has helped inspire. As such, it is not a traditional dungeon, but rather a constantly-changing labyrinth of rooms. There's no knowing where you'll end up when you make it out of your current room; the question is how far you can get, how long you'll survive, and if you can at least die gloriously!

A lot of people have volunteered to help with the Tower, either by writing rooms, DMing one or more shifts at GenCon, or both. There's been a great response both from professional designers and people who simply love the game, and I hope to get more. If you'd like to help out, send me an email at onesmallkeith@gmail.com, and let me know. We can always use more rooms, and I'd certainly love to find a few more people willing to take on a two-hour shift sometime between 12-10 AM.

Looking to rooms, the idea is that each room is, in a way, its own self-contained adventure. It has to connect to the rest of the Tower, and I have clear guidelines explaining the elements a room needs to have; if you're interested, I'll send them to you. Rooms need to be designed for AD&D, but I encourage people not to be scared off by this; even if you haven't touched AD&D for ten years (or ever), it's just not that hard to pick up again. If you don't have the books, take a look at http://www.knights-n-knaves.com/osric/ . We've got enough contributors to run the event, but I'd always like to have more; the Tower is like a memorial quilt, and I'd like to get squares from as many different people as possible.

The challenge is the deadline: I'd like to have rooms by August 1st. While things can be as elaborate as you'd like, at the bottom level we're talking about a single room designed to occupy people for 15 minutes or half an hour, so it's not as crazy as it sounds. So if you're interested in writing a room, or DMing a session at the con, send me an email!

OK, maybe this is a crazy idea, but has there been any thought given to the idea of putting the Tower in some printed form that could be purchased at a later date.  I think it would be fun to have a copy of "The Best of the Tower of Gygax" or some such.  Perhaps it could even be a charitable product. 

I was thinking the same thing, I do not even play D and D any longer but I would buy that just to keep it.

Fat Dragon Games:

Anyone know what room the Tower of Gygax is being run in? Also, is this a ticketed event/need generics?

Yes indeedy, it was a ticketed event. On the ticket it says the ICC: Rm 115.

Not sure about the generics question, but I hope they do take them or there will a lotttt of unhappy folks I think.

Absolutely they will take generics, just like most other events.  It is ticketed, so you could buy tickets, and I suspect some times might sell out on site when people want to go through with their gaming groups, but yes, it will take generics.

Done and done!

Unfortunately it looks like the pre-reg for this event was almost nonexistent.  I think this event was a great idea and hope that interest will increase as we get closer to the con.  It would be great to see every slot full.  I have a group that will signing up for at least a couple of slots when they reopen registration.

I'm planning on wandering in with generics at some point, too. It's too intriguing not to try.
