This pen is a modification of my previous Canvas Parallax Skyline pen, only with mountains this time! This one isn't totally optimized yet though. Still having trouble finding exactly when I can reset a point to the end of the canvas, with the least runoff on the edges. Right now I am overshooting both sides a little bit too much.
