USC grad student John Brennan dropped GamePolitics a line to show us this amazing Half-Life 2 machinima featuring John McCain, Barack Obama, and an authentic HL2 head crab.

By way of explanation, John writes:

I'm an MFA student @ USC's interactive media program.  My thesis project is a series of modifications to Half-Life 2 that will operate in the same space as political cartoons.  I'm playing with format right now, but so far it is Modding and Machinima as self expression and political commentary:)

I have a process for quickly getting 'news-makers' (providing enough photography) into Half-Life 2, access to MoCap data, and some good people helping out.

I'm just launching my first piece now, but it is sizable enough that I'd like to bring it to your attention.  It includes McCain, Obama, a debate stage, and is just in time for the vote.
