The footsteps illusion-like pausing and sticking illusion
The rectangles in the upper half appear to move to the right and stop periodically; however, they are moving to the right at a constant speed in the same way as the rectangles in the lower half.
The two rows of squares are moving to the right at the same speed; however, the top row appears to be moving to the right, while the bottom one appears to be moving to the left.
上下の正方形の列は等速度で右に動いていますが、上の列は右に、下の列は左に動いているように見えます。

The squares may appear to shift vertically or horizontally, but they are actually stationary and perfectly aligned in either vertical or horizontal positions.
