Play with my perlin noise generator by changing the scale (scl) and increment (inc) of the noise. the increment only effects drawing and the scale only effects generation.
if you wan't to use this, you can, but it is just using simple algorithms that you can figure out yourself and it isn't specialized. 6/30/16 - I now output to a list. this means that you can use this for more than just pen, and for this example it means you can scroll. 2/13/17 - It's now actual Perlin noise
