Illusions: Why is it that in some paintings the person/animal's eye seems as if its staring towards us, even when we look from different directions?
That's fascinating! Are there any other illusions in art that you know of?
Yes, there are many! One common illusion is the trompe l'oeil effect, which is when the artist creates an image that looks like it's three-dimensional and popping out of the canvas or wall. Another is the use of foreshortening, which is when an object appears to be shorter or longer than it really is, depending on the angle from which it is viewed.
