Optical illusion (3D)
To make this all we need is just paper, pencil, and 2 bright markers.
Shape your hand with a pencil. Do not push your pencil to make a handshape outline hardly seen.
Once you’re done start drawing your lines from the bottom of your paper. Your lines should be straight as much as possible except the fields where the handshape is located. Once you get to the outline of the hand curve you line like a bridge. Then when you get to your next outline continue your straight line.
Optical Illusions can use color, light, and patterns to create images that can be deceptive or misleading to our brains. Optical illusions simply trick our brains into seeing things that may or may not be real.
