How to draw an impossible pentagon - cool optical illusion by artist Jonathan Harris.
I start by drawing a circle with a compass and then I draw a vertical and a horizontal line through the center of the circle. I then mark out the 5 points of a pentagon and join up the points creating a pentagon shape.. Once you have the basic 5 sided shape down your ready to double up the lines and make it three dimensional. I hope you can see how I create the impossible shape..
