One of the really strong visual motion illusions

[dmm]

Some visual illusions are very strong, this one might be the strongest I've seen yet:

One can place the cursor at various parts of the image to verify that the wire frame is not moving relative to the screen.

I don't know if there is a detailed neuroscience understanding of this one.

I don't know the name of this illusion, but doing Google Image search with this static snapshot brings some of its instances up:

I remember that from a few years ago. There is something about leading/trailing edge detection here.

Possibly relevant:

Twitter does resist downloading gifs from tweets, but apparently there are many ways around this:

Next thing one might ask is how to write one's own code doing this :-)

Good example of how our perception creates an illusion of reality.
