Pavement drawings in perspective

These are pavement drawings. They are NOT 3D objects. But it’s hard to believe. (Even the shadows are perfect.) See more at Julian Beaver’s site.

Infinite depth painting

Have a look at this infinite depth painting. You can zoom in forever. At some point, you realise, you’re back where you’re started. Almost like going around in circles, except that you’re zooming in.

Michael demonstrates an interesting Optical illusion.

On the right you see a circle of blue-violettish (=magenta) patches, one of which briefly disappears, circling around.

Let your gaze rest on the central fixation cross, but observe with your “inner eye” the patches just when they disappear. With good fixation, you should see a strong greenish colour whenever the violet patch has disappeared.

When you are fixating well, after a few cycles you will actually see a rotating green spot! If your gaze is really steady, the magenta patches will disappear, leaving only a rotating green spot!
