I'm not normally the type to post just a link, but I figured this was easier than sending a mass e-mail. Besides, it's 11 a.m., and I think this may just be the coolest thing I'll see all day.
Optimus Prime transforming in CGI test footage from the upcoming Transformers movie.
(edit) My mistake. Turns out it's an audition video for a company that's trying to get the CGI contract for the movie. Still cool as hell, though. Oh, and Prime's not red and blue because of copyright issues, folks.
While I'm at it, here's ILM's audition.
