STOP SIMPLIFYING STRICTLY!!! DO NOT SIMPLIFY ANYTHING! remove all comments! 

advance in this code indices exchange transition animation.


one index shifted towards other = other shifted towards that in position visibly transitioning and emptying that cell in grid while in transition.


interconnect transitionings through indices to all other overall randomness in concept.

strictly let all cells grid indices fluctuate in repositionings transitioning through all other in randomnesses!
