A year after moving into their newly renovated Fifth Avenue apartment, a New York couple received a poem in the mail from their architect, Eric Clough. It directed them to a secret panel containing a book, which in turn led them through 18 puzzles built into their house.

Door knockers removed from the wall connected together to make a crank that opened hidden panels in their dining room credenza. A decorative leather trim spelled a message when wrapped around a removable bar from a bed. Secret panels contained a cloth crossword puzzle, a magnetic cube that opened more secret panels revealing a poem, and more.

He even used Le Corbusier’s Modular Man in a piece of art which contained puzzle pieces. This (not this) is the way a truly star architect should build on the work of Le Corbusier.
