A few tweets from Sarah Hartley gave me an idea for an iphone app:
I’m going to call it iwall and it’s specially designed to give you a portable bit of wall to bang your head against when you are in a meeting.
Taking advantage of the tough build quality of the iphone this little app takes the innovative step of bring the wall to your head rather than your head to the wall. The app will display a high-quality picture of a wall for you to bang against your head and can be set to emit a realistic head on brick sound.
How much shall I charge?
