Dubbed Time to Lead, the sundial is an oval mosaic 20 feet across and 12 feet from top to bottom. The top arc is constructed of ceramic tiles whose colors represent the spectrum from dawn to dusk. Integrated into the spectrum are the numbers of the sundial and images of indigenous animals. The bottom arc is made of flagstone, and the interior features the scene of a tree, mountains and sky made of decomposed granite and aggregate. Within that image are plaques denoting each month of the year.
Attendees can step on a plaque with the current month, and be able to tell time with their shadow.
The 2011 group, Class XX, call themselves Dos Equis, The Most Interesting Class in the World.
