The code suffers from redundancy–it should be broken up into reusable bits–but it creates a nice version of the walk.  It just repeats each step four times and does 8k steps instead of more.

Been working with Processing and came up with these. Its kind of a random walk (the wikipedia article gets into the burly details).  Although it will walk back upon itself as there’s no logic to check if its already been at a certain place and it has no case for standing still which could be added.  But I’m pleased with the results. Three examples then code below.
