I had a number of messages saying people didn't "get" how the bird was folded.
What better time to show everybody?
Start with a square of paper, and copy the folds you see.
Yes, I know I pre-creased the paper, but if I didn't that took the video over 30s unless I sped it up.
I'm also a bit miffed with the end caption - the version I uploaded doesn't have the stray "m" (I wasn't expecting YouTube to mangle it like that).
