9. Anamorphic Illusions
https://www.youtube.com/watch?v=tBNHPk-Lnkk Anamorphosis is basically a distorted image or projection and in this case, the talented people from Busspup confuse you so you don't know if what you're looking at is real or not. You might have come across the effect through 3d street art. Via the Brusspup channel on YouTube, your eyes will seriously be baffled by this. 8. Shade Illusion
https://www.youtube.com/watch?v=z9Sen1HTu5o Another video by Brusspup. This one highlights how your brain adjusts what you see to what it thinks you should be seeing. The two squares are the same colour but because it doesn't make sense to your brain, when the square is in shade, it alters your perception of the colour.
