Two scenes from my student animation project, Bottled Dreams:
Rome's Pantheon, on the computer.
The Blackwell - a Quake 4 multiplayer map.
Deadlock - a map for the venerable videogame Hexen. Still worth a look if you're into the old Doom engine and its offshoots.
My first freeware Doom levels, the Cabal series, here collected sequentially.
