monolith

An obelisk, column, or large statue formed out of a single (mono) stone (-lith).
Or just about anything that's massive and inflexible quality or character.

Also a game company that made Blood and Blood 2 (www.lith.com)

And also ml.org.

A black rectangular prisim with the proportions: 1:4:9. They are supposedly created as tools by a race of super-evolved beings that exist as pure energy (as explained in 3001). Sort of like a cosmic Swiss Army Knife. I wish I had one, but the user interface doesn't look to friendly.

The monoliths are featured mainly in Arthur C. Clarke's Space Odyssey series (2001: A Space Odyssey, 2010: Odyssey Two, 2061: Odyssey Three, and 3001: The Final Odyssey).

Mon"o*lith (?), n. [F. monolithe, L. monolithus consisting of a single stone, Gr. ; single + stone.]

A single stone, especially one of large size, shaped into a pillar, statue, or monument.
