t↦c≡ (t+n)mod26 is a series of videos by Meatsleep. There were three versions of the same video, each one varying in lengths. The videos were all released sometime in October of 2014.
The video shows a still film of a sunset in a big city. The sky shows multiple colours, including orange, yellow, green, blue, and pink. It is a video, even though it is moving too slow to see any movement. A warped song can be heard in the background.
The three different versions of the video use the same portion of the song, but the lengths vary. The first video that was released is one minute and twelve seconds long. The second video released is two minutes and twenty-five seconds long, and the third video is five seconds long.
The title of the video is a formula related to codes and ciphers.
The song playing in the video is 'Hardback (Industry)' by Dizzee Rascal. The song was most likely chosen for the lyrics, which advise the listener to stay anonymous, and never let anyone know anything about you. Meat seems to have taken this advice for their channel.
Don't tell no one where you are, even better if you're far Everybody knows you're a gangster and that Porsche looks great But do you really want it sitting on that council estate Differently watch where you choose to socialise Keep an eye out for trouble, watch for devils in disguise And please don't be fooled by no pretty females Play it safe, never let them know your full details
