This is some pretty cool stuff. Grab a point on the model to drag it. Click file to load a new model. Use the sliders to the left to adjust gravity level and so forth. Notice that there is only one energy point, all other movement keys on that point. You need to have a Java runtime environment installed to view the animation.
