“The Plaza del Torico in Teruel, Spain was renovated (in 2002) with something even better than yellow bricks—over 1230 color-changing LED lamps embedded in the pavement. It’s kind of like that fiber optic pavement you might have seen at an amusement park in the past, only on a larger scale. The whole system can be programmed to change colors and patterns in sequence.”
