I do a fair amount of time-lapse photography as a hobby and one format I really love is the single frame time-lapse. This is where hundreds (or thousands) of images are stitched together into a single picture instead of a video. There are several examples on this blog including trippy clouds, cranes, a living room and a video which is a time-lapse of single frame time-lapses (made from 1,581,120 photos!)
Until recently I shot the frames like I would a regular time-lapse and then combined them into a single photo using some custom software. This is fairly tedious and so I've packaged up the entire process into an Android app. It can shoot from a minute to 24 hours using the front or rear camera and then saves the finished photo.
