The examples given are all of period 2. There are also 5 known babbling brooks with period 4:

The 4 in the first line have 4-cell rotors; they all behave the same, although the rotors have different shapes. The first 3 of them were found by David Buckingham; I don't know when. I found the fourth one in 1994.

The last one has a 6-cell rotor; I found it in 1997.
