I went to Times Square in KL looking for a bookshop. Nobody warned me about the "largest indoor theme park", including a roller coaster which runs near, through, and around a 10-storey high space. As the roller coaster rushes past just a metre away, the floor shakes (and it's really hard to get a steady shot - see the exposure time below!!). I think this is a great idea, although I wouldn't go so far as to say every shopping centre should have one. I only wish my stomach were keen on the idea of having a go.
