Dicty is a big, new word to me. I'll throw out a laysuffers response anyways.
What makes your footage so dictylike? The way particles organize, sometimes moving across other matter that blocks their path, so it can set up into intelligent patterns? I see this in your vids.
What I want to see before I accept the slime mold correlation, and haven't yet from your M samples, is fruiting bodies. Aren't the big mushroom caps the hallmark of dicty? Could a stronger lens possibly get you there?
What is the neat image at 1:41, a fiber? And what are all the little spirals within it? Microfibers? Spirochetes? Microworms? Morgellons fiber motility is all about twisting and spiraling in my experience.
