Notepod is an iPhone graph paper sketchbook. The specs:

Three 60 x 110mm, 100pp Notepods printed on both sides. 80gsm laser throughout with a stiff black strawboard back.

Front: 52mm by 77mm of blank space floating in darkness. Endless possibilities in a form reminiscent of a popular smart phone.

Back: A light 6mm grid, perfect for notes or jotting down the phone number of a hot geek.

I'm getting a set, even though I don't typically do iPhone design. Get yours here.
