Maybe a longer neck? I think it's pretty good as it is actually.

Naturally..

Cool. Maybe we can convert the hippo to a polar bear? It would also be nice
if we make a sinkable iceberg.

Exactly. Possibly the player will have to do the levels in some order, or 
we can have free choice.

I think a real map texture on top of a pov sphere is probably
enough. I can do this model.

I'll have a look at the c library, and then ask you again if needed.

Mm, I'm trying to avoid this. I'll see if the filename matching can be used.

This is more "pure", I agree. I'll clean up the pov directory then.
