If the clouds come up when you are on the 51st floor of the Ponte building in Hillbrow, the light reflects of the red advertising sign above the building, and glow pink. This happened the night I was there, interviewing Nickolaus Bauer. It felt as if the building was wrapped in a pink feather boa. This was part of the inspiration for the TweetingGogo logo. Here you can see the view of the lights of Hillbrow through the pink cloud.
