I took this picture because I thought it was cool that you could see right through the building in the center that they're building. When I looked at the picture later, I realised I'd taken a photo of some kind of parallel dimension, whereby the whole earth was bending. (in reality the cheap digicam i used, has a fairly poor cmos sensor that must take the photo from the top and then scan/read down the sensor, so if you move the camera slightly, the image can change)
