Serious Play Conference: Redmond, WA: August 21-23. Check out all the latest and raddest simulations and serious games at the the sacred halls of the DigiPen Institute. You'll find just about everything here--from your basic Flash math apps to state-of-the-art biofeedback simulations for combat stress and medical training. Yeah, pretty serious--and not the typical commercial-grade games you'll find on store shelves. EdSurge's Tony was there last year.
