Since March 7th of 2013, one mysterious channel has been flooding YouTube with a near constant stream of baffling videos. Even calling them videos is generous—they’re more like blips or brief communiques—although communicating what is anyone’s guess. All exactly 11 seconds long, consisting of a 10 slides with red and blue boxes in varying configurations, 77,000 videos and counting have been uploaded in the last year—literally dozens every day.

The account uploads new videos faster than most Twitter accounts send out tweets—even the really active ones. Clicking on the “recent uploads” page and looking at the succession of time stamps is overwhelming:

It’s like something out of “Lost.” The account, Webdriver Torso, is a total mystery. The “About” page is blank and Kotaku notes that various attempts to make contact with the account owner have proven useless. There has been speculation that the project is someone’s attempt to communicate with aliens. And the constant visual signals, coming through like pings from the ether, do feel like a sci-fi equivalent to the accidental discovery of space’s background radiation on the Holmdel Horn Antenna in 1978 that helped prove the universe is expanding.

There was also a theory that the videos were the product of some company testing out a new technology, but that theory has been debunked. (Who needs 77,000 videos of a few shapes as a test?) And Kotaku puts forth a theory that the account could be a gigantic troll by a few Google employees. Possible, but I’d hope Google employees would have better things to do than clog up YouTube bandwidth with 77,000 videos. And isn’t this a pretty low-fi prank for something launched in 2013? If Google engineers wanted to troll, I’d think they could come up with something better.

The videos do get views. The account has picked up 30,000 subscribers over the last year—no doubt many internet voyeurs hooked by the mystery. But one video uploaded Sunday night had over 200 views within 10 minutes after being uploaded. Even for an account with 30,000 subscribers that seems like a very responsive base—especially given the content.

We don’t have any answers—or even any conjecture really. Webdriver Torso remains one of internet’s most bizarre unsolved mysteries. If you have any suggestions let us know.
