We've all seen people with their heads bowed and faces in their smartphones, merrily oblivious to the world around them as they walk along.
It seems the smart people in Holland have devised a special light which displays at crossings and shows up on the ground showing when it's safe to cross. That way, smartphone users don't need to look up from their important activity. ;)
Risky, imho.
