PD Particles is a software program for sketching, doodling, painting and drawing with particle brushes. It is loaded with features made for professionals, yet priced low enough for retired artists, students and hobbyists at all levels. If you like to draw and doodle, this is for you!
I don't know what particle brushes are but this looks like it could be a fun program for the person who likes to fool around with art programs. Keep in mind that you must download AND install the program today.
