  Sustained rhythmic oscillations, pulsing dynamics, emerge spontaneously when
the local connection scheme is randomised in 3-value cellular automata that
feature"glider" dynamics. Time-plots of pulsing measures maintain a distinct
waveform for each glider rule, and scatter plots of entropy/density and the
density return-map show unique signatures, which have the characteristics of
chaotic strange attractors. We present case studies, possible mechanisms, and
implications for oscillatory networks in biology.
