It's the only tribute that you can only see once a year.

The Anthem Veterans Memorial, located in Anthem, Arizona, is a monument dedicated to honor the service and sacrifice of our armed forces.

According to the Anthem official web site this is how it works,

“At precisely 11:11 a.m. [PT] each Veterans Day (Nov. 11), the sun’s rays pass through the ellipses of the five Armed Services pillars to form a perfect solar spotlight over a mosaic of The Great Seal of the United States.”
