Cacatoo - Diffusion limited aggregation

<!-- 
  ###########################################################################################
    This is a JSFiddle example of "Cacatoo". This HTML page does not contain the code itself,
    but determines where the grids, graphs, buttons, etc are placed. The real code is in the 
    Javascript Tab. I recommend enabling "Tabs (Columns)" under the settings in the top-right.
