Make sure that you use turbo mode! Wow! Renders amazingly fast if you are in the normal sized screen mode! Maybe this will help your problem? Well, I know that I made it a lot less... I don't know, inefficient, but now all it does is draw the bumps in the shortest time possible. Change the slider to get some strange and interesting results. My personal favorite would have to be 5! @person345 did most of it, just made it a bit more efficient...You like it?
