Art Lebedev, the folks at ISBAK, and the city of Istanbul have together designed Isiklarius, traffic lights for punctuation lovers. Shaped like exclamation points, its hoped that they'll stand out in busy Turkish streets.
The concepts are designed to use PHOLED, or phosphorescent organic light-emitting diode, technology and would come with sensors that alert to handicapped persons. And the body itself is modular so you can switch up the signals to reflect what drivers and pedestrians ought to look out for. Pretty neat. [Art Lebedev]
