Wow--this is the real thing. Automatic physics, drag-and-drop color-coded timeline editing, reference grid, multiple undo, tutorial, and a very simple UI that delivers a lot of power without needing a lot of tools to learn. The Editor alone has very lifelike animation--then throw in the juggling editor and you have a list of all moves beside the animations. Click any move and the routine will transition perfectly to the new pattern. It has the look and feel of a real juggling routine.
