Michael Langan's Dahlia is breathtaking. He has inverted animation and instead of creating motion by moving characters or objects across the frame he creates a kind of magical stasis where objects in motion are kept center frame while everything else moves around it. Perspectives shift, landscapes slide past, this is a window into an alternate universe of motion and is beautiful to boot. The film is full of witty and poetic variations and is rewarding in view after view. I think I've watched it ten times... today.
