Live demo

There's a number of settings which can be changed in the url:

• particles
  Sets the number of particles in the simulation. Default is 16000.

• scale
  Ratio of window size to canvas size. The default of 0.5 means that 1 pixel of the canvas is 2x2 pixels on-screen.

• seed
  Sets the initial seed to which particles will attach. Possible values are:

  • center (default)
    One pixel in the center of the screen
  • box
    A seed surrounding the entire screen
  • ground
    A seed running along the bottom
  • sky
    A seed running along the bottom
  • random
    Seeds are randomly placed. The ´randomSeeds´ parameter sets the amount of seeds.

• realtime
  When set to true, each particle will move by only one pixel per simulation frame. When set to false, as many steps will be calculated as possible.
