The BT Tower is 40 this weekend.
One of the photographs I used to make the 360° panorama.
We know how much it weighs, 13,000 tons, as well as the degree to which it is designed to sway, about 8 inches, in winds of up to 100mph. In winter the Tower contracts; in summer it expands by as much as nine inches.Click here for a QuickTime VR panorama I made from photographs I took from the tower a few years ago. Be prepared for a wait - it's a 5MB file made from 40 or so photographs taken from each window on the observation deck while it was stationary. As it was made from a set of 4 Mpixel images there's quite a bit of zoom available too...
