Cel Animation:

"Traditional animation, (or classical animation, cel animation, or hand-drawn animation) is an animation technique where each frame is drawn by hand. The technique was the dominant form of animation in cinema until the advent of computer animation."

"Generally, the characters are drawn on cels and laid over a static background drawing. This reduces the number of times an image has to be redrawn and enables studios to split up the production process to different specialised teams. Using this assembly line way to animate has made it possible to producefilms much more cost-effectively."

I like the idea of hand drawn cel animation, however after attempting it myself in the workshop before easter I soon realised how difficult & time consuming it would actually be...

This video explains how cel animation was made before the use of computers...
