Earlier this year I did animation for this intro. The client was Visual Creatures and John Cranston gave me probably the best experience I've had with a creative director. The look of the piece was great and well-defined, the boards and direction were clear, and the notes I got back were helpful and insightful. I did some bits of design here and there, like tweaking the characters and such, but I was pretty much just an animator on this spot. That doesn't happen very often and it was a nice break from the somewhat rigorous work, art-wise, that I had going on at that point.
Anyway, check out Visual Creatures. They are good people.
