The designer Thanva Tivawong proposes a new design for the traffic light based on the age-old hourglass.
<p>Mark Frauenfelder <a href="http://www.boingboing.net/2010/11/19/hourglass-traffic-li.html">found</a> this <a href="http://www.yankodesign.com/2010/11/18/sands-of-traffic-times/">interesting new traffic light design</a> by Thanva Tivawong. LED lights trickle down like sand in a virtual hourglass, letting you know when the light will change. I actually find this to be pretty confusing the more I look at it—a simple numerical countdown or a design like <a href="http://www.good.is/post/Is-This-a-Better-Traffic-Light-Hard-to-Say">Damjan Stankovic's</a> might be clearer—but Tivawong's proposal does make you think about the opportunities for improving traffic lights.</p>
