Finally got around to playing with my rw-4 was able to get a standing wave going. .. love the way the polyps sway. ..I can't remeber how to embed a video but here is a link. .. turn your volume down as it was noisy in the house when I shot it. . And please ignore the not so 1080p that my 8 year old Samsung galaxy 3 shoots in. .New s7 edge comes next week though so better videos to come. ..
