/*  I wanted to create some cool art for my 3 year old daughter's bedroom
so I took this great random flower program on OpenProcessing.org
(Flowers by Kevin Middleton : http://openprocessing.org/visuals/?visualID=312) 
and added the color taker (inspired by Jared Tarbell) and an SVG export... 
I tried the PDF library and could not get it to export everything.  
ProSVG also had a bug and I had to get an updated version.  
Press "S" to save the files to your sketch's directory

Anyway the color picker is a big add as it allows you to find a image that
you like the "feel" of and mimic it in the flowers...  

I also added the ability to manually add flowers with a mouse click 
if you want to turn of the random placement
