This 3D anamorphic pencil illustration of Newton’s Cradle was sent to us by reader Joshua Stacy. The shading effect on the artwork is so realistic, I almost expect to see the balls clacking together. In fact, if you’re reading this Joshua, I think it would be amazing if you created a few similar drawings that could be put together into an animation of a moving Newton’s Cradle. The result would be eerily unreal. And rest assured, if you did decide to do that, I would eagerly put it up on the site as well.
