Idea 64: "Graffiti for the young" serial magazine
Three gay icons as drawn by renowned dickwad Banksy, yesterday
Graffiti is a well established art form now, and a lot of the techniques used by graffiti artists are intricate and detailed, but not necessarily easy to learn.
But they could be if a weekly serial magazine - much like the kind you get now for astronomy, cooking, horse-riding, that sort of thing - was created which provided young people with stencils and advice on how to achieve the desired effect. On top of spray techniques and styles, it could also have a retrospective of a renowned graffiti artist each week, and easy-to-learn hints and tips on avoiding police capture.
(The first week only costs 95p and you get a nice ring folder with it. Each issue thereafter is £5.95)
Feasibility Rating: oh, I dunno. Shall we way 8? Or 3? One of those.

Forget the idea. I didn't even read it really.
The photo and the caption are pure genius. It's moments like this that make blogs worth reading.
