Yes. Pass by the store's window between 10am and 6pm over the next three weeks and you'll see two creatives from TBWA\London working on briefs, holding meetings and well, just hanging around being creative (while wearing French Connection gear, of course).
The idea came to the pair, Chris Bovill and John Allison, when they realised that a window space at Selfridges is the exact same size as their office at Whitfield street.
There is, of course, a webcam link on chrisandjohninthewindow. com for those of you interested in watching the creative process, which is rumoured to be much more fun than its sister sport, watching paint dry.
Trevor Beattie, the chairman and creative director of TBWA\ London, said: "Ever thought that the ads were sometimes better than the programmes?
Ever wondered how the slick slogan writers come up with their glossy mini-epics? Well, wonder no more. Come visit the brightest young creative team in advertising and see them do their thing, live, before your very eyes.
Bored with the lethargic (lack of) antics of the Yank in a Tank? Come witness Two Lads and a Layout Pad - it's a bit like the David Blaine thing but with an idea. Or ten."
Unlike David Blaine, who has also shunned normal life for living in a glass box, the pair will be eating. In fact, they'll also be having their girlfriends round for a bite to eat on the weekend.
