OF: 2 Particle Systems 1 Sketch

SO COOL!

In this Sketch I coded 2 particle systems that overlap each other. As the mouse hovers over the screen along the x-axis, the square particles spread farther across the screen. When you click on the mouse a new set of circles are generated rising from the bottom of the screen, hitting the top of the screen and returning back to the bottom where they go beyond the the screen height.
