Next in LoL Shield history: a sort of “growth simulation”:

 

  1. Place a particle (say: light a LED) at a random place on the shield.
  2. start a new particle at (0, 0).
  3. move this particle randomly; north, south, east or west.
  4. if the particle hits a placed one, fix it at its last free place.
  5. repeat from 2. until (0, 0) is occupied.
  6. then blink the result, clear the screen and start at 1.

If the movement crosses a border then move to the other side. Mathematically spoken: we are on a torus.
