Stefan Pabst is an accomplished Artist that, as well as drawings and painting very realistic portraits, creates very convincing 3D optical Illusions. I have added Pabst's time lapse videos below, to show you how he does it. Maybe once you see how the illusion is achieved, you might want to try yourself? Enjoy...
