This is an amazing optical illusion

This one doesn't quite seem to work for me.

If I am looking away, at something else, and this is at the corner of my vision, I get a faint sense of seeing something moving there but if I look directly at it—nothing.

A big screen seems to be necessary for this one. I just tested it. A cell-phone sized picture did not work for me either, even when I looked around the image.

It's pretty neat on a big (computer) screen.

"Stepping feet" motion illusion.

Both the yellow and blue rectangles move at constant velocity, but it appears they the do not. Quite striking...

I am impressed with how bent these lines look when in your peripheral vision, and then when you look directly at them, they are perfectly straight and you question your sanity...

Nothing is actually moving except the stick figure running in place.

The color flashes all-at-once; you can confirm by pausing it (windows key - shift - s on a PC).

Yet motion is perceived upwards, to the right, and downwards simultaneously.

Explain it if you can. All I can think of is that that the tiny outlines matter a lot, and we are wired to see movement like that, so we do.

That's a new one to me, absolutely astonishing.
