Ahhhh. Thank you very much for taking the time to give my experimental 
code a go Elijah. I really do appreciate it. Imvvho, it sure does seem 
to expose the bias quite nicely. The dynamic non-intersecting tree, 
without adding any artificial points, grows to the biased directions, so 
to speak. Try to click some points to attract the particles away from 
the corners... It is fun, well to me at least... ;^)

Well, this can be a lot more ordered. The code as-is shows the corners 
of the parametric square basically stealing particles from the middle of 
the lines connecting them. The DLA growth _really_ shows this off. I 
agree with you. Thanks again. :^)

Now, this can go in 3d, this is bound to z-axis 0 prevent the vectors 
from going in 3d, it is like a slice of a higher-dimensional object... 
The following vector field core code of mine can extend into Nd actually...:

I have some 3d renderings up on the Facebook. Are you a member of that 
thing?
