This is cool, Alexander! Thanks for sharing.

I thought I'd mention that at first I was confused because I expected the colors to change automatically when I moved the slider. I did end up figuring out that I needed to drag the paintbrush over the drawing to get it to work, but you may want to think about adding in a little explanation if you ever use something like this in a real course. :)
