Zoom out, Zoom in, animated video

I've been trying to track down a video for some time now, and am hoping
someone here might be able to help me.

It starts with a boy on a small boat, it zooms out farther and farther,
past the planets and the solar system, the galaxy, and keeps going. It
then reverses and zooms back in to the boy, and then continues through the
boy's skin cells, atoms, and so on. It's an animated film, I saw it a few
years ago on T.V. (I live in Canada), and haven't seen it since.

It's an excellent film to help get an idea of the scale of the universe,
and I would love to watch it again, and show my nephew as he's been showing
interest in astronomy lately. Any tips would be much appreciated, thank
you.
