This also from the film '2001'. I really like this design,
It's so real and not fancy.
I found later that it's a very interesting idea to use
a spherical tank for the cockpit. It's a water container. For a big one,
it's bigger enough for 1 person to get inside. It's made from plastic
and easy to deal with it. I'm not sure this kind of water
tank is available or not in another country (I'll take
a photo later if it possible). This idea is suitable to
Spacecraft or Mech cockpit projects.
