Some 2D animators, mostly from Disney, are putting together a short, Hullabaloo. The steampunk art looks fantastic.
Jim Dear??
EDIT: There is a lot of great names, there.
Lopez, Smith, Farmiloe, Lee, Cleuzo, Airriess, and Black have all made some amazing things.
I've heard Lowenthal, and recall him being well.
Falksen looks familiar - have I seen him in something live-action?
A very nice list.
