I realised that using the script I had written to make the maps of Tau Ceti, it would be a simple matter to make an animation giving the illusion of a spinning planet.

Edit: I have now added an animation of Gethen as well.
Edit 2: As an astute reader pointed out below, the original animations spun westward, meaning that the sun would rise in the west and set in the east, contrary to one’s expectation. There is no physical reason why the opposite should be preferred, but it feels more natural, and there is evidence in the books for this interpretation, wherefore I’ve updated the animations.
