I modified my noise modulo sketch from last week by adding a second noisefield perpendicular to the first one. I got this idea from a facebook comment - which unfortunately has been deleted, so I can't credit the author. The two noisefield functions use different offsets and move the field with different speeds to create a more asymetric image
