All the best creative people I've ever worked with have kept scrapbooks. They're always snappers-up of ideas and the physicality of a scrapbook ads something to the process. Plus the unexpected conjunctions you get through the randomness of scrapbooks can lead to some of the best ideas.
I think planners should keep scrapbooks too. I do. You should always have a ton of stuff ready to add life and flavour and texture to creative briefs. And it's a good way of complying with Richard's Diktat Number 7.
But also in there some pictures of some of the stuff we did to make the old building a bit more stimulating.
We attached bungee chords to some of the internal windows so we could stick stuff up. I'm a big believer in sticking stuff up. I think planners should take a lot of responsibility for the internal environment of an agency (or wherever). It's a fantastic way to get ideas and thoughts into the edges of people's attention field. if you beat them over the head with something they'll ignore it. If you stick it on the wall next to their office, or the kettle, they'll put it in their work. (Must tackle that idea in here.)
Anyway. What have you stuck on your walls today?
