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
