Default Illusion images

So you've probably seen these kinds of pictures that are 2-in-1. Like this one: Do you see a bird or a woman?



Does anyone know of a good 3-in-1 picture????? Without flipping it or rotating it.

3/1?

I don't have one, but it would be amazing if there were one!

3-in-1 illusion:


One may see it as:
  1. solid cube with missing corner
  2. cubical room with smaller cube in corner
  3. solid cube with smaller cube in front of it
The third one may be more difficult because the shading is inconsistent; it is as if the larger cube is illuminated by a light source above and to the left, and the smaller cube is illuminated by a light source below and to the right.

The pdf document linked here claims you can make a 3D physical model which yields the same illusions.

With a 3D model, there is an additional aspect to the illusion. In the third view, when the model is rotated, the smaller cube appears to rotate in the opposite direction. This can be seen in the YouTube animation linked here.

These illusions have been attributed to "How to create visual illusions," in The Amateur Scientist column, by C.L. Stong, Scientific American, Nov 1974, though I haven't seen the article to confirm that it mentions the third illusion, the 3D physical model, or the counter-rotation.

This may suffice, thx. The idea is that this can be a figure of the Trinity. The reason I like this analogy is because, unlike the water-vapor-ice analogy, for instance, the 3 figures in this 1 image don't ever go away.

Water-vapor-ice would work -- but only at the triple point!

back to the OP's picture, I clearly saw the bird until the woman's face was mentioned then that is the image I saw. I saw 2 faces and the vase along with the woman and the old man in the other pictures.
those are fun.
