Suddenly the traffic light looks so archaic. Yes, the Virtual Wall is a concept, but regardless it could save lives, especially in cites like NYC, where cabs and other motorist race towards the lights to hit unassuming pedestrians crossing on flash walking sign. One problem, though: lasers need something to reflect off of to be seen. Perhaps man holes could be repositioned in an elongated fashion and spew steam up to catch the laser beams.
Grew up back East, got sick of the cold and headed West. Since I was small I have been pushing buttons - both electronic and human. With an insatiable need for tech I thought "why not start a blog focusing on technology, and use my dislikes and likes to post on gadgets."
