Just to clarify, this was quite tongue in cheek and not created with a view toward being "real". Just fun.
For anyone interested the knot shape was made in Knotplot and the scene created in Vue. Rendering was Vue's new sunlight renderer.
Not really just pushing presets, a little more care and time was taken than that, although I admit that I used less precision than usual on painting in the ecosystem grasses. I do have a baby and a toddler, so art time is short.
