**Similar to Optical Illusion I, this work is also reminiscent of an optical illusion. Here, I explore Bezier curves to create differing lines. Bezier curves are mathematical and computer graphics concepts, similar to a curve, with control points that “pull” the curve towards themselves to create the curvature seen below.**
