That's a classic, same happens with Moon craters that look either convex or concave on photos. And a bit similar to the hollow-face illusion.

The bowls were easy.
Finally, it took several seconds to get the top left tray to flip .

Yeah, I have always found that one screwy on the eyes/brain
Also happens on hilly/mountains views, on, say on google earth

If you hover over the "Illusions" tab, it goes back to 2005.

I saw a tiny fuzzy version of this and I liked it so much I redrew it in vector and added some randomness, it's very simple but mesmerising. I tried it in different colours but monotone looks best, being vector it can be printed at any size. Enjoy.

Another one redrawn, not vector. Simple is always best.
