(for my Kevin Smith fans out there)
but to add something about blender 3d: thing about it is you can create 3d animations and videos with it. Its a cool program but the problem is, if you want to do 3d animation as a career no one is going to hire you cause you're a blender 3d professional (of course thats not being debated here so its a moot point). but auto desk does put out a learning edition of maya. seems pretty good for a free edition of a software like this. but you can't really make any production quality animation on it because they watermark the rendered product.
it's available here if you want to take a look.
and you're looking for the PLE version (personal learning edition).
i hope this helps you out some.
