I remember looking up across Times Square just after New Years in 2000 and seeing the new 60-foot tall LED video display that curved around Nasdaq’s Times Square showroom. It seemed at the time to be akey marker of what the next century would look like. The Nasdaq sign cost $37 million, but we know that the price of semiconductors is crashing toward zero. And sooner or later, nearly every surface in our world is going to be a computer display.
