The mysterious 11-second sequence of red and blue rectangles could easily have been lost, unexplained and unappreciated among YouTube’s plethora of kittens and music videos.
But 28 minutes later Webdriver uploaded an almost identical video, and another an hour after that, and another, until eight months later – apparently happy with nearly 80,000 clips – they fell silent, with 236 hours of video to their name.
Almost all of the uploads follow the same pattern – 10 slides, each with a red rectangle, a blue rectangle and a computer-generated tone.
The shapes change size and the notes change pitch. Each video appears to be unique, but the format stays the same.
