Giles Revell and Matt Willey (of Studio8 Design) got their hands on two original Photofit kits (a nicely tactile process of criminal identification now replaced by digital imaging) and invited a handful of people to attempt to recreate their likenesses with them. Some were featured in Guardian Unlimited late last year, but you can download a PDF of the project in its entirety at the Studio8 website.
A humble thankye to Peter James Field for sending us the link.
