Sliding an L shape three squares to the right

Video description

A static, frontal shot on a light background with a regular grid of equal squares that stays motionless throughout the video. A single solid turquoise L-shaped piece with both arms of the same thickness appears left of centre. For roughly the first second the L does not move; it then travels to the right — at a speed that varies along the way — exactly three squares of the grid, and comes to a smooth stop around the sixth second, staying completely still for approximately the last two seconds. Throughout, it keeps identical size, shape and orientation: it does not rotate or deform. There is no reference outline, no labels, no arrows, no shadows and no people. The scene is silent.
