Programming Challenge 3:
Diffusion Limited Aggregation Growth

MODIFY
Modify the simulation to provide an intuitively improved user interface.
a) introduce one or two RadioGroupBoxes.
Modify the simulation to alter the rules which govern the growth of the colony, e.g.
a) change the criteria which determine when a particle will stick to others.
b) change the regions from which particles are introduced.
c) change the paths along which the particles will wander.

EXPERIMENT and EXPLAIN
What new growth patterns can you produce?
Why do they grow the way they do?
