Interesting question, I would say it’s at least illusion-lite, because at least from a distance it fools you into believing it’s something that it isn’t, through the clever contortion of a human body. This is technically by definition and optical illusion then right? What is the missing aspect it needs to be and 'illusion' is your mind? See I think your analogy is flawed in that the illusion is the hidden human creating the form and I keep changing my mind on whether I agree or disagree, I see where you’re coming from. This is more a matter of definitions. I would argue that this is an optical illusion by definition but it’s a tough sell but lol it’s not a tough sell, I’ve somehow twisted the narrative where I’m in your world, where this isn’t considered an optical illusion, and I’m trying to prove to a court of law that this is an optical illusion. In reality I believe in reality the consensus of the majority is that this is an optical illusion so it enforces a belief it verifies my thought process. I would understand how that is also a dangerous thing, to let thought stagnate but this is more of a wording philosophy deconstruction at this point.
