Poem
Green paper napkin
Like flowers in Japan
A nice origami design
Folded as a sun catcher
It can be a fortuneteller
You can take it as a protection
Or write on your reflexions
Just play with as a kite
up in the air
Sail up there the breeze and go
Whichever it chanced to blow

A 2nd way to sqrt(3) (folded napkin)
