This wonderful photo series comparing the size of things by Kevin Wisbith is a really fun way to earn some brain wrinkles, because it gives you a better sense of the true size of random buildings, ships, machines, and other objects. You get to see things like the Death Star hover over Florida in space, a B-2 bomber stretch across the width of an entire football field, and the Titanic lay out on top of a freaking aircraft carrier.
