In this wallpaper, I will reproduce smoke using a specific GLSL shader.
By looking at real smoke, I get 2 impressions:

1. Smoke is fading while moving away from the source
2. Smoke is spreading while moving away from the source

I can reproduce 1. by fading modifying the alpha transparency value and 2. by scaling the smoke, both depeding on the particle life time.
