Few things are more difficult than designing things for yourself, so I really struggled when creating my own business cards. Eventually I decided it would be fun to create something that focused on my love of op art patterns. Using a combination of only positive and negative Xs and Os, I came up with a concentric, vaguely ocular pattern that is guaranteed to make your vision swim. My good friends at The Half and Half fired up their old Vandercook and printed me up a bunch of letterpress goodness.
