                Beginning to reverse-engineer FizzyText
              
          
    TOTALLY SUPER DUPER NOT MY WORK! Trying to illuminate how FizzyText (seen here, source here, isolated from dat.GUI dependency here) works. Original appears to have been written by George Michael Brower.
In the original, which I find brilliant:

Solid black text is drawn onto an invisible canvas, from which it gets bitmap data
The bitmap data is read like a collision detection array, where black means "you're on top of text" and white means "you're not"
Particles of size r=0 are randomly spawned on a visible canvas
The particles grow if they're on top of a (non-rendered) black pixel, and shrink till they disappear if not
When they shrink to r=0, they respawn randomly somewhere
The particles follow a Perlin noise flow field, a very sensible and fluid kind of random movement, in which nearby particles
