And in related news to the previous post, the first listed entry on Carmack's diary/blog refers to a machinima video his wife's company put together using Quake tools that was selected for a viewer's pick on MTV July 2003. You can find it if you search for "In the Waiting Line" or Zero 7.
Machinima is a digital art that combines traditional animation film with game production techniques, using game engines to produce the cinematic product. For a more coherent and cohesive explanation of the genre, head to Wikipedia for their entry on the phenomenon, including history and links. There's so much more to know about this. Talk about opening a proverbial can of digital worms.
If you're hooked and piqued, check out the Academy of Machinima Arts and Sciences for info and details on their regular festivals. Go on, try your dab hand at something creative.
Alternatively, you can stay in the UK with the Bitfilm festival.
