Frank Warren, compiler of secrets and author of books about the PS project, comes to the University of Texas at Arlington with a multi-media presentation on the phenomenon and stacks of books to sign. More information here. 7PM.
GUITAR HEROES: That's Metalocalypse creator Brendon Small wailing on guitar behind the animated character Skwisgaar Skwigelf on the show.
