Why not...? Idea for a complex Random Walker subroutine.

In conjunction with any number of options for the walk algorithm of a random walker, I came up with an idea I'd be interested in seeing play out, but which I'm too inexperienced to code.

Here's a simple breakdown of the idea, which is a "reproduction" algorithm:

a complex random walker
has 9 children over a period of ten phases, one at each phase but the tenth
a child remains dormant until the tenth phase
on the tenth phase, the 9 children become active and join the first walker in random walks
all 10 walkers proceed to have children over the next 9 phases, and the grandchildren join the walk on the next tenth phase
repeat up to the tenth period

It's a pretty simple ruleset. Anyone is free to adopt it.
