I want to do a little demo with animation in Processing. I would like to show a typical construction facility..For example, a fork lift gathering barrels and placing them on a conveyor belt and another animated robot grabs the object dropped by the fork lift and takes it elsewhere...Is there a library that is good for animations like this? I know about the  Ani Library but it doesn't seem to be capable of doing the animation I mentioned above...Any ideas or tips on what I can do?
