Did Frozen Planet provide inspiration for this, by any chance?
I've been wanting to vessel in ice for years now - I think it was actually inspired by an X-Files episode originally. Something about the isolation is mysterious and spooky. I did put on the latest Frozen Planet to get me in the mood, and not only was there an ice breaker ship but then time lapse footage of the auroras as I was in the middle of painting my own. It was weeeird!
