Ambiguous quartet

In the visual illusion known as the apparent motion quartet, two dots are presented at diagonally opposite corners of an imaginary square. When the pattern alternates between the two diagonals--top left/bottom right followed by top right/bottom left--people perceive the dots as moving back and forth either horizontally or vertically. After a period of time, typically a minute or two, most observers report that the axis of motion appears to flip from vertical to horizontal or vice versa.

Nice interactive animation showing motion detection in our eyes.

From the website: "Click the "animate shape" box to start or stop a shape's movement across the colored background. You can also move a shape by clicking and dragging.

What do you see when you stop the shape inside the colored background? What if it's only partially inside?

Experiment with different shapes and backgrounds, starting and stopping in different places."
