Ben Burtt, sound designer on WALL-E, talks about how he created a universe "from the sound up"

Foley artists are some of the coolest people precisely because not a lot of people know they exist. Originally I had written a bunch about what Foley is and why and how the people that do it are awesome but the first 15 seconds of this video explain it better than I ever could, so just watch it. Highlight: Burtt uses a slinky to create a laser gun noise.

(Be sure to watch Part 2 as well!)
