How can you do animation like cartoon shows, ETC. On a home computer for free?
Blender is quite hard I've tried it. If you have an iPad or iPhone get Animation HD it's easy to use and great quality. Though it costs about $6 I forgot but that's good for an animation program.
if you are a beginner try goanimate and if advanced, try blender.You can also google it and iff you dont know how to use those programs, you can youtube tutorials
