Kind of...
But really, more like dropping a leaf in a stream and then having to predict exactly where it will travel as it heads down the stream, but with the added twists of: The stream is 3 dimensional, not just 2; the leave can change it's characteristics like temperature and form (solid, liquid, gas); and those changes can bring about events like rain, snow, fog, freezing rain, etc.
Oh, and there is actually not just one leaf, but billions of them.
