Every so often, in the course of spotlighting great ideas, we ponderously turn our attention to great mysteries in design. Like: Why aren’t there clocks in airports? Seriously.

Think about that, next time you’re racing for the gate.

On a related note, frequent fliers will appreciate Outside Magazine’s delightful survey of new airport amenities, from complementary napping beds in Dubai to a $10/day lap pool in Munich. But still, no clocks.
