This is a Marionette object that creates an array of festoon strings. The Marionette object has four control points (one for each corner) that allow you to place each corner at a specific location and height. You can adjust the number of strings, the number of arcs in the strings, and the overall depth of the arc. The objects arrayed along the festoon strings are symbols so you can use the ones provided or create your own. The symbols provided have glow or light objects in them, so they can be used in renderings.
