Take a seat!The word is spreading that the very popular AVsitter script system for animating furniture is going open-source from the end of this July (2017). The scripter, Code Violet, announced it publicly and it has been covered in online blogs and forums.
In earlier issues of this column I've discussed special uses of the system. particularly related to the "Experience" it offers to seamlessly attach props. That Experience is one of the more interesting challenges for open-sourcing the script. Fortunately, the existing Experience will continue working (which means the Experience owner will remain a Premium member, to keep the Experience valid). That's fortunate because it means stuff will keep working seamlessly for all the end users who've already agreed to enable the Experience, anywhere it's enabled on the grid.
It also demonstrates some forethought in the design of Experiences in SL. For an Experience to remain trusted by participants, someone must control what functionality is added. If instead it were possible for griefers to extend the AVsitter experience to randomly teleport people or be disruptive in some other way, residents wouldn't keep the Experience enabled, which would squander the "network effect" of its ever-growing base of enabled users.
