To build a folly is essentially to do something a second time, something at an inopportune moment. That something is always the memory of something forgotten, about which we can paradoxically say "There it is again."
Follies were misunderstood, purposeless constructions. They were often only small, extravagant gestures in a garden, easily whisking off the imagination to distant lands, a sort of time capsule built to awaken the memory and induce surprise in passers-by. They marked locations, organized secondary paths in a park, or simply predicted the arrival of better times—a demarcation, a sacred spot, a mysterious trail, a hill whose tragic rocky nature begged for a tower, a party, or the arrival of summer.
“It is demonstrably true that things cannot be other than as they are. For, everything having been made for a purpose, everything is necessarily for the best purpose.” — Professor Pangloss
Students traditionally learn art and design by studying the masters, analyzing, sketching and interpreting the grand visions of the past. In doing this, they get to understand the ideas, concepts and motivations behind the visual form.
In user interface design, this practice is curiously absent.
Compared to other design disciplines, interface design is ephemeral. You can still buy the Lounge Chair that was designed by Ray and Charles Eames in 1956. But we cannot enjoy the beautiful Calcbot app from 2010 on a current iPhone because the latest version of the operating system simply won’t run older apps.
