As revealed here last week, Channel 4 has commissioned four leading imagemakers to adorn a giant 4 logo outside its headquarters. First up, photographer Nick Knight whose contribution was unveiled today: a
9-step lenticular using images of eleven different bodies.

Apparently, "the idea for the piece was to reflect the channel as a multicultural, responsive entity". According to Knight's ShowStudio website, "in response to your movement, the bodies appear to gently heave and writhe to a subtle heartbeat soundtrack created by SHOWstudio contributor Nick Ryan."

The 48-feet-high steel number 4 was erected last week.

Designed by Freestate, in conjunction with engineers, Atelier One, and built by The Mike Smith Studio, it will mirror the channel’s award-winning idents with steel bars forming the 4 logo only when viewed from a certain angle. Over the next year, four different artists have been given the challenge of decorating it: after Knight, will come Mark Titchner, shortlisted for the Turner Prize in 2006 and Ghanaian sculptor El-Anatsui. The fourth artist will be the winner of a competition open to young arts graduates, run in conjunction with the Saatchi Gallery.
