From Michael Mills of the New Times:

Just in case you don't pick up on it the instant you walk in, the key to "Nathan Sawaya: The Art of the Brick" can be found in a sculpture on the far side of the main gallery. It consists of a roughly six-foot-tall reproduction of a pencil, standing upright and "writing" one word on the big pad at its base: fun, created in graceful cursive script that leaves no doubt about the artist's intent.
