Different types of animation:

Here are some examples of different means of animating...

• Stop-motion-Whiteboard-Verry effective as you can always see the image of the last thing drawn and change and alter it easily becasuse of simple erasing possibilities.
  

• Rotoscoping(Rotoscoping is an animation technique in which animators trace over live-action film movement, frame by frame, for use in animated films)-wikipedia, An interesting outcome but I feel the method to be too bland and lacks in imagination compared to other methods. Rotoscoping basically means later painting over real film stills. A full length film called 'A scanner Darkly' was made using this technique.
  

• Computer animation (use of computer animation software), most likely the easiest method.
  

Traditional (by hand sketches, later putting the stills together in sequence)-This technique dominated cinema until it was made near extinct by computer software...however I still apreciate this technique because the hard work put in has more soul than computer methods.

HOW TO ANIMATE TRADITIONALLY (...a handy tutorial)-'Cel animation' made obcelete in the 90s by computers

On inspection you may see that Disney have re-used some of their templates for cel-animation...this slightly spoilt my childhood memories...
