- Assuming that I understand what you're talking about and that my math is
- correct:
-
- Consider the point (-1,0). The next term you get is (0,0), then (-1,0)
- (Or am I in the julia set? Oh well, if I'm making a fool of myself
- someone will tell me and I will be wiser.) To the direct right of this,
- the line that is on the inside of the set continues, with projections up
- and down.
-
-
- It doesn't go any farther left than this, I believe, because the
- iteration gitters but slowly grows larger...
-
- A question of my own: What of the protrusion (Not shown in the above
- drawing) from the right of the M set, towards the center. Just how far
- left does this go? To just short of (0,0)?

- Glad to help, hope I was at least sorta close.
