Description: "WIP graphical relationship script sequencer for Sketchup. Ruby scripts can be placed into containers and these containers can be connected. The graph can then evaluate and create a sequence of these scripts based on what has changed. Simple demo showing graph to sketchup and sketchup to graph callback when entity changed and induce re-evaluation of its related containers in the graph." says Eric C.
Also Eric C. says: "the bezier curve creation and manipulation shown in the video is done with a plugin by Fredo6". You can find that plugin Here.
