As for the poll, I voted "I don't think so". In terms of the number of individual things that God has created and will re-create, there is more of everything else than there is of humanity. But in terms of importance and significance, we are the main thing that Christ's life gives new life to. So I have to say that we are not a small chapter.
As for the OP, I honestly don't visualize heaven (nor do I visualize hell). I think that most people's doctrine of heaven comes from the end of Revelation, and I don't think that concrete doctrine as to the exact nature of heaven can be made from that. It's a highly symbolic book, and I think that the last few chapters are no different. And frankly (not to be cynical), I really don't care what it's like.
Now, as a few others have said, I do think, since all of creation will be renewed, that our experience of heaven will be tied in intimately with an experience of the physical creation.
If my hunch of God's plan is right, then I think that all of creation will be renewed because all of creation (especially ourselves) will "become partakers of the divine nature". I think that God will unite all of creation to Himself, and thus everywhere in the universe will be "heaven".
And although I respect someone's own private vision of heaven, I won't tie that into my own doctrine of heaven. Even if I were to see a vision of it myself, I don't know if I would make even my own vision my doctrine, for who knows whether God was showing me a symbol of the real thing or the real thing itself.
