Images reinterpreted by particles. The direction of each particle changes according to different calculations that use the brightness gradient of the image as an input.

Variations:
Particles speed, initial moving direction, and the way they interact with the image.
5 different selfies, 5 color modes, 5 dark background colors and a mirror mode.

Press "P" to toggle particle mode.

Inspired by some works of Leonardo Solaas.
