As a direct rezult of a
FB update here is my unfinished
POV-Ray code,
like with no spell checking or anything:
/*
while in the begining I thought to add this to wikipedia as a wasy to describe multidimensional space
I was actually more interested in researching which diods would best correspont to the human eye.
The ones that emmittid photons at the wavelength that our cone photoreceptors can most easely convert into electerical energy for interpretation by the brain.
You see I'm a chemist and the most fun thing about chemistry is the funky colours, particularly the organometalic coordination complexes.
but in the end this document became programming practice, particularly for my comments. And when I realised that I tried to make the program more effecient too.

being the first place I declare these variables I should explain
all the dimensional translations are based on a sine waveform

the red color dimension 100% and move the x axis as far away from the origen as possible.
