Additionally, I tried a quick search for the HDTV ad he describes and found this, which I thought was pretty inspired:
Maybe we could have a few animators from Aardman do a special one now, say Wallace & Gromit hunting were-playdoh-bunnies across the streets of Manhattan. I can really see it being really cool.
