It is invented by anyone who has an idea of what kind illusion that they are going to make and understand the way that a human mind work and also more of a fun trick that can share with your friends. To me, I find optical illusion creative because its allow us play with people minds with just visual images whether it is fun and impressive or scary and creepy
