I happened to be at a very tall building just beside the ArtScience Museum.
I could not resist not taking a photo of it again. I took and posted a photo of it once here.
So that's where the lights are placed. It produces such a nice glow to the so called 'lotus' leaves.
Rainwater is harvested and channeled down the big 'sink plug' you see in the photo. Part of that water is used in their toilets.
I have not been in there, but I want to go there one of these days before the current exhibition ends.
I must make time to visit the Shipwrecked Tangs Treasures on display now. Must find out which credit card gives discount for the entrance ticket. ;-)
