   ROOM II · THE STYLE FORGE · 2011 · Kelsey Advertising & Design

   Two years at an ad agency in LaGrange, GA teach you that the best ideas
   hide in plain sight, usually in the style guide. One custom property below
   is never used by any element. Agencies call that "brand equity."

   It has been rotated thirteen places, the way a junior designer rotates a
   logo until the client says "the first one." Rotate it back.

   Then go somewhere robots are told not to.
