Here is something that will astonish you, it may look creepy though, yet its fun looking at it. You might think its magic, but I assure you its all illusion, I know so, because I actually made one, and it really works. At first glance, the head did not appear to be moving, but as I stare longer while moving from different directions, suddenly, it started following me, shifting its head from various angles. Its really amazing.
Would you like to have the 3D Illusion Dog and know its secret?
