Yellow Dog: Animators benefit from home computer power

It is how lots of individual digital stills or computer generated environments become moving images.

Now Bristol start-up YellowDog has found a new solution, harnessing the unused power of ordinary home computers.

The BBC's Dave Harvey met the inventor, Gareth Williams, and Justin Dowling, one of the thousands of animators who get frustrated waiting hours for films to render.
