If it ever starts to not look like a swastika, I just continue the pattern outward. Anyone who wants to try it you just use a random number generator to pick a predominate color. Than a random number generator flips a coin for predominate or not. If not, pick a random color. If it were continued outward, before you create a second one you would just pick a predominate predominate color. It takes advantage of human's ability to see patterns and try to continue them, and human's inability to create randomness on their own. If they try to obscure it with a solid color they will continue the pattern. If they try to randomize it, unless they are using a computer they will fail and structure will show through.
