One of the great things about where I work (besides getting paid every other week consistently) is the access to experts and professionals and places in a very creative industry. It allows for some wonderful experiences in learning. I have been able to visit Pixar about three times this year I think and this Easter Sunday had a presentation with David Levy, a Sr. Concept Artist who worked on Tron Legacy (we also both happen to be game industry veterans from Acclaim Studios). You have to commend a talented person that shares his knowledge and gives up his time on an Easter Sunday (it was a last minute change from Saturday to Sunday due to water main fixes in Emeryville)
David Levy's website is at: http://www.vyle-art.com/
and his blog is here: http://vyle-art.blogspot.com/
and his teaser for his film Plug: http://www.steambotstudios.com/plug/
I highly recommend taking a look at his work and visual style!
