I don't usually brag too much about the Professional Association for SQL Server (PASS), but I think they did a very slick little promo video. Check it out here: http://www.sqlpass.org/summit/Flash.cfm.
Oh, and if you're thinking about going to the big 2006 PASS Summit this year, I encourage you to register sooner rather than later. Registrations are very strong and this could become a sell-out event if the current trend continues. Check for details at http://www.sqlpass.org/events/summit06/index.cfm.
