There is a large variety of oscillators (mainly billiard tables) with numerous different periods. Some of these periods are the result of several separate rotors being connected by the same stator, such as this impressive natural p168 object with four separate rotors:

Code: Select all

`x = 34, y = 19, rule = B2ci3ai/S2-i3`

However, there are also numerous non-trivial high-period rotors, such as these four (p21, p26, p30, p33):

`x = 63, y = 14, rule = B2ci3ai/S2-i3`

There are also XOR-based one-dimensional rotors, such as this natural p62:

`x = 14, y = 15, rule = B2ci3ai/S2-i3`

There are several natural c/4 diagonal spaceships:

And finally, there is natural infinite growth in the form of several different wickstretchers:

`x = 54, y = 18, rule = B2ci3ai/S2-i3`
