Twitter Trends Why clutter street corners more than they already
are, when the Wearable Signal Walking Sign can be fixed to any
existing lamp post, traffic light, or even tree?  The shield of
this innovative concept for an intersection has a surface of
solar panels, which powers the flexible strip of LED lights.
Designed by Jaemin Lee, Gisung Han and Hwanju Jeon, the Wearable
Signal Walking Sign tells pedestrians when it's safe to use the
crosswalk, requiring no electricity and no additional
installation of poles.
