Press Space to change the backdrop. This is a continuation of my last project, where I use "Perlin Noise" (basically randomness but smooth) to create semi-realistic terrain. This is a simple demonstration of how terrain is actually generated in video games. What I did here was take a bunch of layers (The blue through yellow ones) and stack them on top of each other making the green line. If you want to make it better in some way, remix!
