That's fantastic, I was wondering whether it was actually images or just randomly blinking LEDs that this effect read too much into until the RCMP image came up. Amazing.
I used to live on Queen's Quay and saw it pretty much every night. At first it was only the solid colours blinking and racing up and down the tower, but one day it was really obvious that there was a picture involved - it looked like the edge of the screen of a worn out VHS recording. A while later, this video was made, so finally my curiosity was satisfied.
