Picked up a new term. :)

I am amazed at how artists can visualize something like this. And I do get that what you see is a matter of perspective.

I remember reading a perspective book years ago that explained how to do something like this... (I think)...
But I can't remember the name of the book lol

Nice

That’s wild

Cool

There's a company that makes cups and saucers that do this ....it's clever🤗

It lost its appeal to me when I figured that computers can do that and anyone can print it out on a piece of paper in a heartbeat... It's a cool effect though
