A designer imagines hourglass-inspired traffic lights.
I can’t resist a piece on the reinvention of ordinary objects, and this is an exemplar design. While it doesn’t really need an explanation, here it is anyway:
Using LEDs to mimic the trickle down effect of the sand-filled glass, these lights provide a quick visual cue for how long you have before the color changes.
It’s especially important to note the use of LEDs for the stoplight, which for current stoplights has been a terribly slow implementation by counties.
