One day i strolled up and down the street. i saw a little girl about 5-7 years with her mum.
i pulled out my wallet, tooked a small sheet of paper and folded a swan, like the one you see on this picture.
her eyes became bigger and bigger and finally i gave it to her.
she said something like: "mum, it´s the same swan we saw in the zoo"
i said: "not quite correct, this one is free- and able to fly"
Its the Origami Swan (Robert J. Lang).
Folded by me of 8cmx8cm, 15cmx15cm printer paper.
