Foo field #10

After a year of studies on the flow field, I thought it was time to create something, which to say the first time I saw the ff was love at first sight.
the core of the algorithm defines a ff class that generates a grid of vectors representing a ff and a Particle class that follows the flow field and moves around the canvas accordingly.
then I worked on a background made of vertex, and on the colors and textures that form the field
here a little ex. of ff
