I had the idea of using the awesome and very well done Many Circles by Rachel Duim with flowers instead of circles or spheres, and the best usable and configurable flowers I could find are from the Day of the Dead also by Rachel Duim
It started simple, and was to be going a simple thing, but then I have been working very much making it much more complex and better with more options and be more flexible and more detailed as this is what FF is about and to be able to customize it as you may want, and it has taken much time to make it right and well.
Here is a first test of the version 3.0 that will be available when I can finish it
You can spray flowers over the original source image that have transparency, here is the FF Lionfish
And although these ones here are drawn flowers, I have the idea to use a modified version to use REAL true photo flowers for the same spray effect.
