pan-lapse film and a stripy 360° panorama. However, one can push this game even further. The above image type is also know as "little planet," since there's sky all around a landscape photograph.
It is essential to make the left and right edges of a panorama match exactly to get the impression of a continuous image. The above image was created from the "cloudy sky" stripy panorama of KAIRA. The image was loaded into the open-source image manipulation software Gimp, and then turned into this circular panorama using the distortion filter "polar co-ordinates." It's a pretty cool effect.
