while looking quite similar to the flower conky I posted a little while ago, I have made some significant changes.
Previously the flower color change "effect" was created by placing a circle that changed size in response to a numerical input from say, cpu usage, behind a flower "cutout".
That's why it was on a black background, and would only work on a flat monotone background. Otherwise you would have this:
it was all an illusion! 
...but i still really like this version
but with the updated version I have used the data output to transform some much more complicated shapes so that the "cutout" is no longer needed.
each flower has 4 components, background "petals" bg, indicator "petals" in, middle circle, md and a single back flower shape bk. I included bk so that on busy wallpapers you could set bka (alpha) high to allow the bg petal overlap, if thats what you wanted, without the wallpaper showing through.
here is the code:

local delim_from, delim_to = string.find( self, delimiter, from )
while delim_from do
table.insert( result, string.sub( self, from , delim_from-1 ) )
from = delim_to + 1
delim_from, delim_to = string.find( self, delimiter, from )
end
table.insert( result, string.sub( self, from ) )
return result
