In their first couple of years the New Adventures covered surrealism, cyberpunk, high fantasy, space opera, a Quatermass pastiche, and even a right-wing religious authoritarian mystical horror novel (The Pit, which arguably took Doctor Who into places it should never have gone). Lucifer Rising was the NAs’ first Big Dumb Object novel.
Big Dumb Objects are one of your standard SF tropes—what Rudy Rucker calls “power chords,” the ideas that are to SF what the hooks are to a pop song. BDOs are the coolest gadgets in science fiction—both artifacts and environments. Rendezvous With Rama’s vast wandering starship is the canonical example. (And one of the blander ones, to my mind… although it’s been years since I read it and if I went back I might have a different experience.) My favorite is Stanislaw Lem’s Solaris (from Solaris, natch). It might be stretching a point to class a living planet as a BDO, but Solaris does the same thing: injects Sense of Wonder straight into the novel’s jugular and gives the characters something mind-blowing to explore and react against.
