Art Lebedev Studios has introduced it’s Luxofor traffic light prototype, with square lenses that are lit up by superbright diodes to make it them more visible to drivers and pedestrians. As usual, a million of you have slapped your head and asked “Why didn’t I think of that?”

The square light fills up the same space taken up by a round lens more completely. It’s just a concept right now, but the Art Lebedev team wants to cooperation with road safety councils and local authorities to improve and design road markings and signs. What will the team think of next?

This bit of public art blends nature with traffic in one confusing sculture. It’s Pierre Vivant’s Traffic Light Tree. A giant sculpture of fully-functioning traffic lights in London. For some reason it’s parked next to a roundabout near Canary Wharf.

It was created by the Public Art Commissions Agency and it’s sure to confuse tourists, since roundabouts are confusing all by themselves. Remember the Griswolds in that Vacation movie? The light cycles of the Tree/Traffic Light mimic the action of Canary Wharf, imitating the landscape, while the light patterns match the rhythm of the domestic, financial and commercial goings on. Pretty strange, but neat.
