tl;dr: A photographer realized their habit of taking many near-identical shots from slightly different angles meant their camera roll was full of accidental "wigglegrams" (stereoscopic GIFs made from looping similar frames). They wrote a script using perceptual hashing and Hamming distance to automatically find clusters of similar photos in their iCloud library and stitch them into wigglegrams. The script is available on GitHub and works on Mac iCloud libraries or any directory of images.
