Description of video

♐LOCK is mostly black with colors occasionally flashing and revealing a single black pixel within each frame.


At the start of the video, the Unknown Voice spells out the word “LOCK”. The audio is in stereo with many strange sounds, heard separately in the left and right channels.

Unusually, this is the only known UFSC video at a 48K sample rate (as opposed to 44.1K)


Frame composite discovery

On April 20, 2016, Reddit user tomasf.se discovered that when each individual frame of the video is combined into an image with a width of 197 pixels, a picture appears. It is currently unknown what the image portrays, but many users have tampered with the image in search of a more clear visual.
