39 seconds of crosswalk signals in Melbourne

The sound of several audible crosswalk signals at this intersection in Melbourne, Australia is not unlike that of a marina full of boats at night. The echo-y polyrhythms sound, to me, just like a bunch of halyards slapping against masts as the boats get hit by passing wakes at different times and intensities. (Not Dad’s boat, of course. He always had the courtesy to secure his halyards with a bungee hooked to the shrouds.

(I was curious, so I looked it up. Accessible Pedestrian Signals have been in Australia since the 1980s.)
