The HPER building here at Indiana University is the school's old gym. It's actually three buildings: the Men's Gymnasium, built in 1917, the Ora L. Wildermuth Intramural Center, built in 1928, and the HPER addition, built in 1961. HPER stands for "health, physical education, and recreation," and today I learned that the building's name is pronounced "hyper" when I made the mistake of calling it "aytchPER." Anyway, if you enter the building through the oldest part—the Men's Gymnasium—you'll find yourself in an absolutely beautifully tiled hallway.

Well, it turns out there's an issue with some of the tiles. See if you can spot it:

From a prominently displayed sign in the hallway:

This wing of the HPER building was built in 1917, before the Nazi party popularly adopted the swastika as its national symbol of world domination. This symbol has been found in many cultures through the world. A various times in history, it has been associated with agriculture and points of a compass, the action and original of the universe, or the succession of the generations.... Only with the rise to power was the meaning of the swastika associated with abusive power and horrible domination. These tiles are not intended to be associated with such meanings. They were placed here with the original intent of wishing health and prosperity to all.

Thank you for your understanding and cooperation.

But some people don't understand...
