I was lent a book (thanks @ackygirl, must remember to return it) that contains some designs I have been meaning to try – the Rhino looked impossible:

The head of this beastie has some 15 layers of paper in it, bending it puts stress on photocopy paper (it began to split up neat the ears) but I like the body formation, it has the cutest little hooves and tail. The body armor looks right (as my feeble memory allows me to remember the last one I saw at Western Plains Zoo).

I was mightily pleased when this model worked first-fold, as there is a bit of guesswork needed to get the proportions right – it looks rhino-y tho so I am happy with the first fold.
