Singapore is packed with skyscrapers and iconic architecture so I guess this one just gets lost in the crowd since despite tons of Google and Wikipedia searches I can't identify it.
Its main feature of interest is a huge glass pyramid on top which looks to be quite a few stories high. At night the pyramid is lit and subtly changes colours.
I realize there are plenty of other buildings with aerial views of Singapore so I'm not looking for "Try the XYZ instead" answers. I want to know specifically the name of this particular pyramid-topped building and I want to know if it's possible to visit the pyramid part.
