I've had a stab at this. Not perfect, but it's getting there. Not sure how this works but I think you'll need to stick all the attachments, including the transparent png into a folder in your search path. There are overlaid matrix controls and you may need to load the transparent png as the cell image file in the input matrix's property inspector.
It has pretty much the same functionality as Otomata save that (i) cells can be freed when they "oscillate" together using the toggles, (ii) you can adjust speed, and (iii) there is a maximum of 8 cells. Once all cells are activated, clicking on the grid changes the route of the existing cells in sequence (1 to 8).
It's easy enough, if laborious, to add functionality for further cells. There must be a less timing consuming way to do this, but it is beyond my capabilities.
Let me know what you think, and any tips and suggestions are most welcome!
