No Animals Were Hurt
A film about Alan Turing presented 1 frame per user at a time. You have to hit it on the right date or just after the 5000 viewer to see the whole thing.
Not sure why they are doing it this way but..
From the site:
Each unique visitor unlocks one frame, out of the total 5000. Each time 5000 is exceeded, the counter is reset, at which time a full version will be available for the next 24 hours. Currently, after 15946 visitors, the film is 19% its proper length.
