There’s some great morph animation in this ad, very smooth stuff. I’d love to be able to tell you what medium this is. To me it looks like CG paying homage to Stop Motion (a la Flushed Away), but I could be totally wrong. Any information on the artists/studio involved would be nice so I can give credit where it’s due.
Update: Tom Mathieson has informed me the studio behind this ad is Nexus Productions.
