Do rants about animation count as fandom related? Surely there are those that are fans of animation, in a non-specific way rather than singleing out one specific group or company.

In that light, Polygon Pictures. One of THE oldest CG Animation companies, not only in Japan, but world wide as well. They have some really impressive stuff.
I was given the chance to watch an episode of Polygon Family, and I'd have to say that if you're ever given the same oppurtunity, not to pass it up. It was rather amusing and interestingly done while not weighing down the viewer with excessive visual detail and complexity.
On the opposite front, Crocotires looks rather visually stimulating.
If anyone happens to know where I can obtain a DVD of their work, I'd appreciate it. Preferably with an english interface.
