"Nielsen has a wonderfully fantastic ability to coherently interrelate the smallest scales of his chaos art, creating beauty with a new concept of edge."
James A. Yorke 

Emeritus Distinguished Professor of Mathematics and Physics, University of Maryland

​"Nielsen has a very sophisticated theory of conception behind his painting of deep symbolic mathematical foundations related to our biology. Incorporating fractals (regularly repeating patterns) and spiritual mythology to stimulate our creativity and internal rhythms, Nielsen’s paintings have an extensive and fascinating etymology."
Ruthie Tucker
