On the Amiga, this was usually used to move the vector table to fastRAM, enabling somewhat faster interrupt processing. One of the utilities that allowed this was VBRMove. I usually have VBRMove…
So, we have rendered frames of our BoingBall, as described in Part 1. What you want to do next is check if the animation is seamless – that is, if it loops without glitches. Best way is to convert the frames into a .gif or .avi animation (in my experience GIF works better) with your favorite photo / video editor. You will also need to reduce the number of colors of your frames, I used just…

The BoingBall is quite famous in the Amiga land, as it was featured in one of the first demos made for the Amiga computer to demonstrate its capabilities at the Consumer Electronics Show in January 1984.
