Probably a svastika somewhere in the movie.
Andy, have you played Portal and Portal 2?
I completed Portal last night and it is easily the best game I've ever played. Can't wait to try Portal 2, which I just bought on sale on Steam.
It is a great use of the Source engine, with neat graphics, fine humor and fiendishly difficult levels and puzzles, but not impossible to an old guy like me.
The whole idea of a portal-creating gun is pure genius. The humor part is provided by the IA character GLaDOS, a voice that acts as a narrator and guide for players undergoinf testing. Her voice is robotic, but distinctly female. She uses a very perfunctory corporate speak but the contents is twisted.
Examples:
GlaDOS: Please be advised that a noticeable taste of blood is not part of any test protocol but is an unintended side effect of the Aperture Science Material Emancipation Grid, which may, in semi-rare cases, emancipate dental fillings, crowns, tooth enamel, and teeth.
GLaDOS: The Enrichment Center promises to always provide a safe testing environment. In dangerous testing environments, the Enrichment Center promises to always provide useful advice. For instance: the floor here will kill you. Try to avoid it.
GLaDOS: Please note that we have added a consequence for failure. Any contact with the chamber floor will result in an unsatisfactory mark on your official testing record,
followed by death.
***EDIT: I just noticed that Tomala's avatar above is GLaDOS
