Thanx !

The biggest problem with my generator is the fact it is nearly uncontrollable, a
can weight the growing direction using random, last direction up and down
vectors, twig len and thickness, chance to split and last but not least the
seed base. Every little change results in a totally different "grow". I think,
some adjustments to these parameters will bring a better ivy :) ... Distant
wall<->ivy, you are right, I will make this controllable by 2 new parameters :)
