Designing Interactions is a really cool, 700+ page, full colour book written by Bill Moggridge - one of the founders of IDEO. It contains interviews with a bunch of top notch interaction designers, and explains a lot of processes and feats designing modern technology from the past couple of decades; everything from designing the mouse to modern video games is covered here.

I recommend checking out this book if you have even the slightest interest in design. Props to Drew for pointing this one out to me.
