Your talk can be about a program, a system, a technique, some hardware - or about a cool project, or some strange idea. You may also give us an idea about your real talk, announce your workshop or tell us about your booth. Or you could simply ask people to join you for some DOS attack of the next food store, announcing a key signing party, or maybe a *real* party. Whatever it is... be brief. Four minutes is all you get, possibly five if the audience likes you!
Slides all run from one machine, see the SIGINT wiki for more instructions!
