As far back as I can remember, I've loved numbers. The number four, in particular, has a lot of character: - Four is the only cardinal numeral in the English language that has the same number of letters as its number value. - The fourth finger (ring finger) of a human hand automatically bends when the little finger bends (trying is believing). - In Tetris, a game named for the Greek word for four, every shape in the game is formed of four square blocks. Herein are five photographic interpretations of four.
