I actually could try to code something up in the weekend. I have some experience with generated images.
Last year I made an oligodendrocyte-generator for an image at Karolinska that somehow ended up on a mouse-mat without anyone telling me (lesson learned: using a creative commons attribution license doesn’t mean they have to tell you they used your work - not that I mind, but I could have bragged about it way earlier! :P). I probably can re-use the code and try if I can get something properly “synaptic” out of it
