A great example of some video compositing, motion tracking, and CG work, this is a video that seems to be related to the Half-Life story (based on the sound effects and visuals).  It’s not completed, but still pretty interesting to watch.  It’s from the group behind “What’s in the box?”

Just a note, this is a demo of their final product.  Many effects are still missing, as is the main character Dialog.  Because of this, the owner says he will take it down shortly.. So watch it while you can!
