Spend enough time studying design and you will begin to look at the world differently. You don't just buy a coke, you see all the work that went into making the label on the can. Open a menu at Denny's and all of the sudden you're seeing the guidelines the designer put in to keep the Sandwiches in line with the Burgers. In a way it's kinda cool, and in another way really annoying.

Since the design world is so often about variety, some of these are organized by project and contain multiple variants of the same idea.
