The more I look at these, the more I'm taken by the feeling that what I'm looking at was not only formed by nature, but colonized by nature in a seemingly random way that has a mind of its own - apart from the artist. It is this "mind" that creates a lot of natural process art, and as an artist I can tell you that it is a joy and a wonder to work with, once you can forge a relationship with it.
I do not think that this particular artist copies mold colonial distribution exactly, mapping them all out using mathematical coordinates, but there's an overall feeling that says "this is natural", not a placement that feels labored over, or over-considered, and that requires an artist for which the natural world, its preservation and presentation, is more important than the ego, or the will of the artist.
As someone that used to work with various fungi in biomedical research -- very lifelike! I had never heard of natural process art, but love the idea of being able to have one of these above my apartment desk to match my lab bench. Thanks for sharing :)
