Titles that show two teenagers exchanging their teen-tribe identity, including chavs, posh, hip-hop, plastic and goth.

Design company: Mr and Mrs Smith

Client: Alchemy TV

How it was done: The titles use animation and retro styling. The stop-frame animation, created by Susie Jones, allowed each look to morph into the next. The sequence was shot in-camera at 12 frames per second almost in its entirety, with the logo animation being the only element animated in post. Maggie Rogers designed and directed the sequence.

Watch it: From noon on Saturday 6 September on BBC2.
