I forgot to mention that you can view videos of a few of the seminars from last year’s Animation Expo on the official website. There are about twenty clips to watch and they only represent a small portion of what was available to attendees. You can also find a few more videos on Vimeo.com (just serach for “CTN Animation Expo”). Most of the videos are not very artwork-heavy which I imagine is due to legal copyright concerns. But there’s still a lot of great animation-related info to be enjoyed.
My understanding is that some videos from this year’s Expo will also be uploaded to the website soon so you might want to check back.
