   fizzlemaster3000.js is a drawing tool
   which creates grass-like vectors (fizzles)
   shooting out of the drawn path.
   
   you can set values like the direction
   those fizzles should point at, the
   growth/lenght of the generated vectors,
   their value of disturbance and the
   amount of fizzles created per mousedrag.
