Hack a Day have been accepting entries to their Sci-Fi contest for long enough that they have a few worth showing off before the entry deadline of April 29th, specifically the Valve themed ones.  A table top sized level 1 sentry gun from TF2 is being entered, perhaps not as heavy duty as  the one currently guarding Valve HQ but destined to be able to fire paint balls if all goes to plan.  There is a French team who are modifying some personal assistant software called RORI into a replica of GLaDOS, hopefully a version at least slightly less murderous than the original while another team is going about creating a physical version of the homicidal AI complete with a camera to allow face tracking.  Check these entrants and other in the full Hack a Day post.

"While most of the entries to our Sci-Fi contest come from movies and TV shows, a select few are based on the Valve universe, including a few builds based on Portal and Team Fortress 2."
