When I was visiting Taipei (precisely this time last year), there’s an intersection where at one point the pedestrians can cross the intersection diagonally (it’s near the Taipei City Hall). I thought it was peculiar because I’ve never seen it before. Just now I ran across the traffic light page on Wikipedia, it turns out that these type of intersections have a special name, called pedestrian scrambles.
The moral of the story is, you learn something new every time you read Wikipedia.
