CG fireworks

This video I found is pretty cool and definitely falls into the category of "stuff I could probably pull off in Ater Effects" at this point. It's a clip shot on a 5D of everyday objects being kicked or shot into the air, exploding into fireworks. The concept of the video is clever but the execution seems very easy. It seems that all you have to do is use something like Mocha to track motion in the frame and place a pre-made firework effect on a tracked point within the frame, and then mask/clone out the ball after the explosion until it leaves frame. Can't wait until the summer when I have enough free time to go out and experiment with stuff like this.
