Hearing that Burj Dubai is now officially the tallest tower on earth makes me wonder how it will look like when it´s finished and shining at night. As we saw the Petronas Towers recently, it´s hard to imagine a structure topping it by another 350 metres or more. It will even make Taipei 101 look dwarfish, I guess. But still this sort of fame is temporary, as the proposal of Al Burj is a high end tree of 1200 metres. Base jumping anyone?
