Watch Time-Lapse Photography of Nail Growth (1960) : Full Movie Online Free Made at what is now Imperial College School of Medicine, this film was intended to document the effects of Glaxo’s Griseofulvin drug on a ringworm-infected thumbnail (although to the untrained eye it looks distinctly like a toe!) over a period of six months. Out of context, the gruesome close-up and mesmerising time-lapse photography evoke an art installation or avant-garde body horror film.
