Cool. Very interesting-looking. If I only could
read frequencies in a foreign measurement system.

I'm kinda toying with an idea that involves
translating between spectral power distributions
and regualr ol' RGB tuples. You sound like
someone who could help.

(FWIW, I'm gathering data over time, and FFT-ing
it, and want to represent the FFT as a single
block of color instead of a bunch of vertical
lines -- i.e. rapidly-changing data appears red,
slowly-changing data appears blue and
randomly-changing data appears kinda gray-ish)

I know (or think) you can multiply n frequencies
( in a 1-by-n matrix) by an n-by-3 matrix and end
up with a 1-by-3 matrix of RGB values.

Trouble is, I have no idea of a perceptually
useful value for n (I've heard 31, but not sure
why), and even less idea what the values within
the matrix actually ought to be.

I've gotten this far by Google and liberal
application of basic principles. I wonder if you
have some hard data (or something) that could
help fill in my blanks.

Thanks,
