Who designed the "Unibody" MacBook?

Apple's industrial design for the last several years has been performed entirely in-house by Apple's Industrial Design Group, led by Jonathan Ive.

How is the "Unibody" MacBook created from one piece of aluminum?

Apple explains that the product:

Starts its life as a solid piece of aluminum. Each aluminum core is precisely machined into the basic unibody design. Another pass and the unibody takes shape. Another, and the integrated keyboard emerges. It takes multiple CNC milling operations to create the complete MacBook unibody.

Ultimately, this new production method results in an extremely sleek, sturdy, and thin notebook.
