Dennis Muren and Pixar!

In an interview with Dennis Muren at vfxworld.com, he discusses work he's doing at Pixar. I'd love to know what ideas he has on pushing the medium! Here's the excerpt where he's discussing it:

BD: You mentioned earlier that you're working part-time at Pixar. What are you doing with them?

DM: Making some suggestions and ideas on some of the visuals. I had some ideas that would give them a different kind of look. So I'm just in there a day or two a week, looking at stuff and talking about it without mucking it up. Their palette is so beautiful. It's just a fantastically artistic place. The CG films that they make are so aesthetically great...and that's one of the reasons I was drawn to them, as well as the stories being so great.
