This illusion is used often in fields like augmented reality, including some kind of shading to show that it has some sort of spacial tether to the real world. In the GIF below, the robots come out of the black space in the middle of the pod that supposedly burst through the wall. This gives the pod the illusion of depth, making it not seem strange to us that things can fit inside or crawl out of it.
Is this a good/useful/informative piece of content to include in the project? Have your say!
