Diary: Cracked in 60 seconds

A creative team at the Manchester agency Driven has decided that spending days strategically developing and perfecting clients' briefs is a waste of time.

So, in their spare time, Nick Entwistle and James Clancy have challenged themselves to complete any given brief in one minute. Anyone can send them a brief on Twitter and they'll try to solve it in less than 60 seconds. Briefs cracked so far include one for Wonga.com and another for WKD, which features a picture of a naked Prince Harry in a hotel room with his modesty covered by WKD's logo. Follow their progress on @oneminutebriefs.
