The format for the talks is called PechaKucha, it started with architect/designers in Japan in 2003 and has spread around the world. Each speaker gets 20 slides and each slide is up for 20 second - no more, no less, so each talk runs 6 minutes 40 seconds. The PechaKucha Seattle event this Friday looks amazing.
The other one I mentioned is Ignite Seattle. http://www.igniteseattle.com/
