This version is outdated. Go to my profile (click my username) to see the newest version. USE TURBO MODE ON THE FLASH PLAYER! (shift click the green flag, you need a Scratch account for this). Press space to render. This is the first step to a 3d terrain generator I'm working on that is made entirely up of cubes. Alpha 2 was a big improvement over alpha 1, adding stone, dirt, and water, but I will keep adding more. Leave suggestions in the comments. If you want the program to go completely crazy, hold down space. Otherwise, I wouldn't suggest it.
