How to do computer animation when your machine just isn’t fast enough? You create a really slow animation, film the screen and then speed it up, as this video from 1985 demonstrates.

Of course there’s nothing old-fashioned about the technique itself; animation movies like Shrek, Happy Feet, Ice Age etc. are not real-time animations either. It takes a lot of time and computers working at the same time to render each frame in such a movie. And it will stay like this for quite some time into the future, because as computers are becoming faster, the images will become better looking, demanding more processing power.
