If you like puzzle games, odds are you loved Portal. For as simple a game as it was I certainly spent my share of hours frustratingly mashing the mouse to try and get every achievement I could. Thus, I was a little excited to learn that Valve was working on a sequel for the game. Now, some more details on what the sequel will entail are being released, or at least leaked, following a casting call. The details suggest that the game may be a prequel of sorts and that it's definitely going to be larger in scope than the original (admittedly short) title was.

If you're interested in reading about it, Kotaku has the details of a voice role and some minor information about the game. The 1-paragraph blurb alone makes it sound interesting enough to look forward to.
