Quake physics mod?

[Box]

I am looking for a Quake physics mod\code, which would allow stuff like solid objects manipulation interaction and weight balance, which would enable creating physics puzzles similar to HL2`s. Engine or gamecode doesnt matter, but have to have src available so I could plug it into my mod.
From what I gathered about the state or Gyro and Twig they cant do such things.
If not q1 maybe q2\q3?

Darkplaces supports ODE iirc.
