Candle pixels La Scala Illuminata.

This picture is of La Scala Illuminata in Caltagirone, Italy. The staircase was built in 1608 and is 142 steps (and thus 142 pixels) high. My guess is that it’s about 70 pixels wide. The pixels, as you can see from the photo on the right, are really candles. The display is shown yearly for two days in July and two days in August — a maximum frame rate of 4 frames per year !
