You thought Space Invaders! was a cool sample, check out this one: It is a VB 2005 Console based game that rocks. http://www.heroicadventure.com/
It reminds me of sitting in my Dad’s lab at NCSU playing Castle on one of the consoles connected to a mainframe.. Anyone of a .NET port of Castle?
BTW – thanks to Joel for pointing it out to me in his trip report from TechEd
