A new Pixopedia 2014 plug-in available on download page (CmlInfector.zip). Various image effects using cellular automata and coupled map lattice models.
There is a bunch of parameters associated with this plug-in (quite a mess), so first try some predefined effects before trying to explore various parameter settings. Because this version is not optimized nor threaded, avoid high iteration values and first try to apply effect on smaller image region (drag on image view to create rectangular selection) before applying effect on complete image.
Please visit Pixopedia FB page for some cool examples.
