At Adaptive Path’s San Francisco studio, we had a fussy refrigerator that wouldn’t always latch when it was shut. Sometimes the fridge would sit open for hours, spoiling food and wasting all the unicorn tears and panda fur oil, before someone would discover it had been left open.
Like any good tinkerers we fixed the problem with technology, devising an alarm that would let us know when the fridge had been left open for too long. Whenever the pleasant sound of the 80s echoed through the office, we knew the fridge needed our attention.
