Did you ever wonder how Apple makes its unibody MacBooks and iMacs so tough, durable and so uniformly beautiful? Ever wonder how Apple manages to make their iPods so colorful?

Have you ever wondered how your iPhone knows up from down, or when you’re shaking it? It’s all because of the tiny accelerometer chip inside the device, but how does it work? It’s not like the iPhone’s got a metal ball bearing rolling between two points in there, so what gives?
