If you think we are not in our senses and that it's a weird way to say fun, then here goes-it's a free 2D physics simulation we gave out on the April '08 DVD. In short, you draw objects like you would on paper and all the drawings react with each other as though they are real. There's a lot to play around with, but where do you begin?
understanding The Phundamental Operations Before we start, here's a very basic introduction on how you handle objects and the workspace in Phun. You can create objects by clicking on the shapes in the toolbar on the left, and then clicking and dragging the scene. To draw your own custom shapes, choose the Brush tool and draw a shape but make sure you complete the loop. To rotate an object, right-click on the object and move it.

In typical empty scenes, there is no ground. Use the plane tool to draw a plane or all your objects will fall through empty space. If you want objects to be attached in the space, then click on the Fixate tool and click on the object created. When you have all the obje<;:ts in place, you can press the Play button under Control. Everything now in the scene will react in real-time. To move objects around, you need to click the Drag tool. To navigate around the workspace, right-click and drag the scene. The mouse scroll can be used to zoom in and out.
