Maelstrom is a particle system simulator. It includes 25 unique patterns. When active, it randomly cycles through all selected patterns, smoothly transitioning between them, often with breathtaking results.

Using the simple interface, you can adjust many settings, including the number, size and shape of the particles. You can also select your favorite patterns, and how long each pattern will run before Maelstrom begins transitioning to the next one.

Maelstrom is also available as a Screen Saver--you can download it from our web site ( and experiment with 4 of the patterns for free. After the App has been installed, all 25 patterns in the screen saver will be enabled automatically.

The patterns include:
  • Blizzard
  • Colliding Galaxies
  • Comets
  • Cygnus X-1
  • Earth
  • Figure Skaters
  • Fireworks
  • Flying Embers
  • Fountains
  • Jellyfish
  • Kaleidoscope
  • Mauna Loa
  • Plasma Filaments
  • Prism
  • Raindrops
  • Ring Fountain
  • Saturn
  • Spiral Galaxy
  • The Final Frontier
  • Torus Knot
  • Trees
  • Waterfall
  • Waterspout
  • Waves
  • Wormhole

    Whether it's modeling the destruction of a star by a black hole, a raging volcano, fireworks, or even growing trees, you're sure to agree that it is one of the most amazing and original programs you've ever seen.
