I wanted to see what it would be like using Perlin Noise to generate the source image prior to generating an RDS. My implementation works heavily off of the JS source code used in the very helpful demo found here: http://eastfarthing.com/blog/2015-04-21-noise/
However, as this version of Perlin Noise is not periodic, I must keep it at a high granularity to minimize the artifacts which arise:
