The quintessential hacker movie, War Games, is celebrating its 25th anniversary this year with a special 1-night only showing on the big screen. (Wired ran a feature article about the movie today, as well.)
There is a Planypus event page where you can sign up (to let me know to look for you/save you a seat in our section), with a link to buy tickets online.
If we get a big enough crowd, we can do a happy hour/dinner before or after the movie. Perhaps a WOPR at Burger King.
