There are rectangle that look like pixels.
These move as they flow.
These are not a single pixel.
If you stop the frame, you will see that they live in half a rectangle.
However this canvas is painted on 500 x 500 pixels.
The information is read to determine the color of the next square.
The flowing pixels seem to anamnesis the idea.
