Check or uncheck the boxes, drag the slider, and move around the points! Have fun. :)
I've seen a couple of these projects recently, one by @Greatguy123, and one by @nwhi. I was inspired by both of those to create this! The main reason I created this was because I wanted one where I could see the curve in real-time, rather than waiting for it to generate. In order to do that, I had to figure out a very fast way to draw the curve. This is the fastest way I could come up with (I'm sure someone else has figured this out before me, but I didn't use any tutorials or code from other people.)
