Didn't much enjoy listening to it

I'm guessing that something's going on here... something beyond my understanding.

I listened to it a few times. Loops well and if it was being used for atmospheric noise in, say, a warehouse scene in a game or film, it might work well.

But I can't say I particularly enjoyed listening to it (mainly because of what it is - just sorta atmospheric noise) and its usage seems like it'd be fairly specialised.

The whirring that pops up around 1:50 is a tad annoying.

Anyway, I was wondering if you could enlighten me. Is that all it is? Is it just meant to be used as sorta ambient atmospheric noise? Or is this some sorta code-making thing, or some technical puzzle or music game?
