Particles is an interactive particle system - a field of dots that are attracted to your touch. All the rules of physics, such as momentum and friction, apply. To use, simply touch the field of dots and they will accelerate towards your finger. Depending on how you touch it, you can create a literally infinite number of beautiful patterns.
***** UPDATE *****
You asked, we listened - you now have full control over the number of particles, as well as gravity and friction, as well as the ability to invert gravity (particles are repelled by your finger). Also, Particles now supports multi-touch, so you can interact with it in more ways!
Please note that Particles is designed to run on iPhone 3GS, iPhone 4, iPod touch generations 3 and 4 and iPad. Due to the nature of the animations in Particles, Particles may run poorly on earlier devices.
