Yes, Analog I do understand the levity of your understatement and I agree completely.  I do know that generic renderers are available online in one form or another for public consumption but it amazes me when I read:  “…for me fractals are just fodder for my first love, rendering systems.” Lycium explaining to Twinbee how he rendered the fractal image using his renderer based on MLT algorithm.  Then I go on to learn that the MLT stands for Metropolis Light Transport method…a rendering algorithm based on the Monte Carlo simulation method both being methods of computational physics used in rendering systems. Fascinating stuff offered up in that Fractalforums link including but not limited to:
