"We gave him a full overhaul," says Hulin. "We were so into it, we bought our own pet gecko for texture and animation reference purposes. Using a mixture of Alias Maya, Apple Shake and mental ray rendering, we gave him a better skin shader, which gives his skin texture a more realistic quality. The agency wanted him to have very human gestures; he's just a regular bloke, after all. We broke away from the very precise anatomical proportions and giving him slightly longer arms and legs that we could articulate to make him more expressive. The lip sync was also quite challenging; he does a lot of talking in 30 seconds, and his cockney accent causes him to combine several words in one go. It's a very subtle style of animation for a spot like this. It’s been great fun to do."
