# Searching for the "blue bird" (glider :)

We can use random initial clusters to find oscillators and gliders. Choose
big enough grid (since glider dies at the boundary) or use periodic boundary
conditions. Set "Delay" = 100. Reset random cluster if all balls die.
I've got stable and oscillating structures for R = (5 5 5 4), (6 6 6 3),
(7 7 7 3) ... But I didn't find glider.

**Press & Drag** mouse to rotate a life form.

Press **Enter** to set new parameters values from the text fields.
You can choose any grid size **N**. The applet will restore the initial
"ooo" structure when you change N.

Selector **Periodic** turns on/off periodic boundary conditions.

Press the **Set** button to set your own initial "life form".
A blue ball will turn into a red one if you click it by mouse and vice versa
(you need to hit into the center of a red ball).
**R**ules:

*a new ball will appear* if the number of neighbors (*Sum*)
is equal or more than *r1* and equal or less than *r2*.

*a ball will die* if the *Sum* is more than *r3* or
less than *r4*.
