I have tried it. It's insufficient. Here is the section from the Wiki:
And going back to the Tree-Cabin example in the Wiki, if you are laying down on the ground and see the top of a pine tree on one side of your vision and the top of a cabin on the other, connecting them together with a string across your sphere of vision does NOT prove that the tree is pointing at the cabin.
I'm sorry you were unable to perform on understand the moon-tilt illusion demonstration correctly, but let me try and explain it again.
I think some of the confusion is due to the TFES Wiki badly misunderstanding the illusion. Here is a quote.
Some attribute this phenomenon to 'perspective', while astronomers tell us that there is a 'celestial sphere' which the celestial bodies glide upon at different angles, and upon which straight lines become curved. We are given a series of analogies and explanations separate from, and incompatible with, the Round Earth Theory.
I am not sure where any of that came from, this is not how the moon-tilt illusion is explained. The entire Wiki page seems to be a straw-man argument as I've never seen a 'series of explanations' to such a simple optical illusion.
The simple explanation is that wide angle images either from a camera or the human eye will result in a distorted image. Adding a reference when taking the photo or looking with your eye, usually a string running perpendicular to the Moon's terminator will show it is actually lined up correctly.
Let me take some pictures to illustrate because this really is a simple concept. Now, you might look at the first image and wonder why light is curving. The shadow clearly doesn't line up with the light source! How confusing, how could this be? But it's just an illusion as the second image shows. This is simply how light works. The shadow isn't bent in that top image, the image is.
Just to make clear, the only change between the two images was framing the image at the top of the sensor vs the center. Nothing else moved, the light and shadow is always going in a straight line. It's just showing what happens when an image is projected onto a plane, like a camera sensor or our retina.
As you can see, there is no need to invoke celestial spheres, things gliding, bendy light, or complicated perspective equations. It's just distortion that any camera or eye will cause. That's all.
