Hello everyone, I am new to the forum and have been interested in Processing for quite a while, I am a 3D artist which doesn't help me at all at trying to learn programming language (: but I am trying my best! 

I want to make a generative pattern program that gives the user an option to the colour scheme and shape of the pattern but still maintain a bit of randomness to the whole thing. The problem is that I cannot make the cells rotate individually when Box mode is on. which will result in whole a lot different patterns. That is in the last if/else statement. Hope you understand. Sorry if my code is messy.

 Thank you!
