Just sit back and watch as this program draws patterns based on numbers. The number of the pattern is in the corner, if you want to know. Note: some patterns (especially #90) may resemble swastika's. This is by no means my intent, and is merely a result of the way this program works. Note 2: numbers divisible by 8 are excluded, as they all result in an infinitely long line pattern.
This was a result of me playing around with the Pen blocks. When I found this way of making symmetrical patterns, I then tried to find a good way to color it. I ended up using a function that calculates the distance to the center.
