Going through presentation mediums

I know of three possible softwares to use in order to create this educational animation; these are the only methods I have seen used in the competition as well:

• Maya: 3-d animation
• Flash: 2-d animation
• Power point: 2-d sideshow
  

These have been examined as a part of brainstorming; my conclusion from this was to use flash for all of my alternative solutions.
