Here is an interesting new product. Developed by the Royal Shakespeare Company it is a motion dampening device for hanging moving lights on positions that might move in response to the fixture moving. A device like this could allow you to hang fixtures on a batten and not have the batten move when the fixtures do. Here is a link to the article: Introducing the RCS LightLock, by Andy Ciddor and a link to info from the RSC site: Royal Shakespeare Company : RSC Lightlock
