CSU's biennial Futurevisions conference is on Thursday, April 12, 2012 at the Lory Student Center at Colorado State University. They have a number of interesting speakers and sessions this year, including David Pogue of the New York Times, and David Ferrucci of IBM's "Watson" (Jeopardy! champion).
Since I couldn't find a schedule anywhere online, here it is, at least as of March 28.
Note: There is no charge for attending.
