Oh come on, give him some credit. It is easier to feature ships from movies and comics since they are already designed and he does have some notable literary spaceships in his list (feel free to send him more! ^^).
I mean for example RAMA was always different in my head, sure I was lured by the cover of the books, but in the end I always saw it with a different design from the inside.
What I want to say is that it is kind of hard to agree on the looks of a spaceship when it's only described in a book.
That RAMA is in the works as a film is something that I am really looking forward to! ^^
Btw. I have a nice new SciFi Movie from Switzerland for you guys, it ain't that great, but it is a Scifi nevertheless and a new one at that. I will give you a review after work today.
