I designed this model over ten years ago, and have incorporated a few tweaks into the design over the years. I have probably folded it more than any other origami model. There is currently one sitting on the Paediatric Accident and Emergency desk (or 'Emergency room' for our USA chums) in the hospital which I currently work in, along with a camel, a pig, a few dinos, and some daffodils folded when I was working on Mother's day (UK date).
Here is a link to some diagrams:
