What do you get when you combine the graphic design geekdom of kerning letter pairs with the pacing of Tetris? Answer: The KERN iPhone App by FORMation. Letters must be inserted with pinpoint precision into place within words. A hair too far to the left or right and you’ll loose a life (measured in ligatures). Available from the iTunes Store for 99 cents. The words themselves are graphic design themed. Props for giving tribute to Rudy Vanderlans (of Emigre fame) among others. Video demo after the jump.
