Highly suggest downloading Dia. It’s so easy to use and makes cool stuff like this in a few minutes. On a Philosophy group, the owner gave a difficult question about a guy creating a clone of himself, and asked “which one of them is more real?”
Hard question. So, I broke it down based on what he said, which was long and involved. Anyway, in just a few minutes, I was able to whip this up. Dia – look it up. It’s free, I’ve mentioned it before but I really like it and it makes cool stuff like this easy.
