Press space to generate new noise. Drag the screen with the mouse if you are zoomed in. zoom in and out with the zoom slider. Set resolution higher if you want the screen to paint faster. Lower if you want a clearer image. interpolation will be linear when 0 and sine wave interpolation when 1
I found a cool project by @tsulej that used a list called perlin_noise256: http://scratch.mit.edu/projects/16758441/ (press 5 when running her program to see the pattern that uses the perlin noise list). So I looked up Perlin noise. I found an algorithm and tried to implement it.
