Look inside, everything is explained there. But the basic agenda is to create a 2d graph... that changes and looks good! You have one line of code to do this, which means that you can only calculate everything using one line to make the line you see on screen right now.
Looks like epic maths I haven't learned yet :( At least this turned out ok. I HAVE NO IDEA HOW I DID THIS. I don't even know if I followed the rules. Eh, I was just having a bita fun. Hope you like it. Enjoy!
