Egg and Mother have come up trumps again with the first TV commercial in an extension of their kooky poster campaign. The new forty second spot is a witty take on the age-old controversial 'animal testing' issue.

The audience is given a sneaky peek at Egg's "research lab", where they test their credit card on Guinea Pigs dressed in human clothing, making their purchases in a tiny rodent world built by the dodgy 'Euro-scientists'.

The interior lab elements were shot on green screen, then the Flame team composited in a 3D model city built by Adam Leary. Textures were simplified in the Cityscapes to give an impression of an unsophisticated, purpose-built guinea pig environment. Finally, two weeks were spent in Flame* painstakingly compositing Guinea Pigs' heads onto the human bodies dressed in Guinea Pig suits.

The result is a really fun, watchable ad that's bound to be a hit with consumers.
