ANN: Kaleidoscopes for all seasons

[James Hurley]

On the theory that one cannot have too many cookies (the real kind)  
or kaleidoscopes (the artificial kind) in one's  life, I  here offer  
my final (I hope) entry in the latter category.

It features two different methods, each with its own advantages. One  
can draw or paint the figures (the latter thanks to critical input  
from Bernd Niggemann.)

If the pattern  is drawn (using Run Rev graphic lines) the resolution  
is quite good but the coloration is limited. If the pattern is  
painted (using the curve pen  tool) the resolution is not as clean,  
but there is more flexibility in the choice of color along  the line,  
something that cannot be done with a graphic line.

I found a somewhat unsatisfactory solution to my earlier post  
requesting a formula to translate color frequency into RGB color  
coefficients. I found  an image of the color spectrum on the  web. It  
was a rectangle ranging from red on the left to violet on the right.  
By extracting the first line of imagedata  I obtained the RGB numbers  
for the spectrum.  This list of 400 lines of RGB data was inserted  
into a custom card property. As one draws out a line in the  
Kaleidoscope the colors are drawn sequentially from this list so that  
the line ranges (relatively smoothly) from red through the spectrum  
to violet. It is not as smooth as I would like, but it was quick and  
painless.
