Kenneth Chang at The New York Times has created a neat slideshow highlighting some of the intriguing puzzles hidden in the Kern Center. The puzzles were designed by assistant professor of computer science and game design Ira Fay, and installed in coordination with the design and construction team. Fay incorporated diverse sources of inspiration, and many of the puzzles relate to the themes of the Living Building Challenge. You can check out the puzzles and get a few clues here, or better yet, visit the building and get sleuthing!
