According to New World Encyclopedia: “Where there is a brightness contrast across the grout line, a small scale asymmetry occurs whereby half the dark and light tiles move toward each other forming small wedges. Our brain perceives these diagonal lines due to the way our neurons interact, as different types of neurons react to light and dark. The white circles appear to form a circular shape that rolls around the inside of the circumference of the red circle. If it's too thin or removed, the Café Wall Illusion no longer works. (Image credit: Brusspup via YouTube) Created by Brusspup, the first optical illusion in our list is a bit of a geometric trick. Interesting, the grout between the tiles is fundamental.

The illusion is even more evident when the grid is created with alternating black and white squares. It was noted that the tile pattern outside the cafe created an optical illusion where straight, parallel lines between staggered rows of dark and light bricks appear to slope diagonally.

Though it is interesting that when people first perceive the dancer as moving clockwise, they have a harder time seeing her switch direction. The optical illusion has been erroneously called a test to see if viewers predominantly use the left or right side of the brain. For instance, the dancer's arms can be perceived as moving between her and the viewer, but also as moving behind her body. Why? The silhouette has a lack of depth thanks to missing visual cues. Expressing your artistic skills through illusions calls for the stroke of genius. And portraying an optical illusion into an aesthetically pleasing work of art requires a fair bit of sense and sensibility. Instead, others will perceive a counterclockwise spin. 65 Amazing Optical Illusion Pictures by The Design Work ApCreating optical illusions is an art in itself. Web designer Nobuyuki Kayahara created the Spinning Dancer illusion in 2003, and the majority of people see her spinning in a clockwise motion. But what if you found out that not everyone sees her moving in the same direction? In fact, some people-if they look long enough-will even see her switch directions.

To understand why these types of lines matter, how to use them based on their functions and discover line variations for art and design keep reading. Other types of lines are simply variations of the five main ones. As you look at this image of a dancer twirling round and round, you might not think you are seeing something special. There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines.
