The video named “♐” was posted to the original youtube account on January 5, 2016. (It was the first video posted in 2016.)
Against a black background with some “fingerprint” dots, the Unknown Voice says “1 0 x 1 0”.
This video had the same phrase “10 x 10” as in the youtube description field. (the only other known video with a description was ♐BRILL B.)
It is possible that this was a prompt from UFSC to arrange images in a grid.
