I also fixed a few minor issues with it and so it looks cleaner.

i had to golf this code to get the original d/19898 under 140, but lost the "focal point" effect achieved here. In need of a shorter way to compute the (euclidean) distance from the focal point (defined by "d" in the code).

please excuse my poor etiquette for i have now learned about code blocks and replacing EVAL with THROW to display compressed code, and the Discord for chat : )
