Since I’m in a hurry right now, I’ll just post a quick relative sizes picture today. Nothing we haven’t already seen. Well, there was a slight modification, though. Normally, we’re used seeing this type of illusions, where further object seemed bigger than the closer one. In reality they were both the same size. I modified the original photo, where both robots were identical in size, and made the further one much smaller in height. This prevents us from seeing him bigger, as we normally would, but I dare to say no-one can perceive him smaller than the victim he is chasing. In worst case scenario, they both appear the same. When you look at the second picture, you’ll realize how they are different indeed. This “advanced” type of relative sizes illusion, can already be seen in Xaver Nitsch’s Audi R8 example.
