Today I have a very interesting lesson on the mythical Ouroboros that someone requested. This symbol is recognized by a snake or dragon eating their own tail forming a perfect circle, or figure eight shape. Here is "how to draw Ouroboros", step by step. Another meaning for the Ouroboros is self reliance, self-reflexivity and also represents how something keep recycling in the same manner without change. You could say it's like looking at an infinite shape where something continues but never ends. I think you will enjoy this tutorial because it's both cool and well recognized. Adios amigos and have fun.
