What always amazes me about this things is not so much how they work or that they work at all. It's more that they are so completely simple. The brain is such a curious thing.
beware mind/body dualism: instead say "my model of reality is such a curious thing".
Why? It's clumsy and not colloquial. It's the properties of the the brain we're talking about. I see no mind-body dualism implied by saying "the brain is such a curious thing".
Dualism is just fine in casual conversation. Avoid it in science.
Who has the model now? And who was engaging in dualism? :D
It's not my model of reality because it's not conscious thought that is responsible for the illusion.
Actually... this illusion gets better. Move your HEAD left and right along the horizontal axis of the illusion. The angles would seem to change because you feel like you are moving across a place with two buildings.
