Particle Field
A matrix of vectors acting upon a field of particles. Reminiscent of falling water or snow, slightly. Click and drag to ‘draw’ vectors on the field to influence the movement of particles.
For me, the idea comes from Charles Forman’s blog post in Setpixel from 2004, “Snow is fun.” Which is incredibly great. And done in Processing.

Mesmerizing. I’d love to see it with a ‘save/load vector matix’ option.
awesome experiment.
beautiful!
What you do is really quite amazing! We work in 3D and we use particle effects too. Here’s an example. http://www.media-freaks.com/inhouse-animation-projects/tornado-special-vfx-mediafreaks.html
