It’s a PDF to download. Not tried this one yet, so I can’t comment on how difficult it is, but those ears can’t be easy 😉
Update: Sam’s just downloaded it, and it turns out there’s an added twist to the challenge – it’s in Spanish. Still, if you fancy having a go at some papiroflexia, you can always work on your language skills at the same time.
Update2: Boing Boing have just added a link to some origami models of satellites and such like – this time the language challenge is Japanese. Good luck. I give up.
