Pulsus is an eye pleasing online game developed in Flash, Actionscript and Pure Data by Anthony Mattox, taking inspiration by his previous work with particle system on Processing. Anthony wrote about the development of Pulsus on his blog.
“The game, Pulsus, is a puzzle game about particle systems. Players have to place objects to direct particles from emitters into goals. While it is a puzzle game, it is also about exploring a dynamic system.”
It remembers me a little bit of another game called Auditorium.
