I learned to make paper origami cranes when I was young. After World War II, my father was stationed in Okinawa, where he learned to appreciate Japanese culture. When he retired from the Marines, he brought home several paper origami cranes from Vietnam which we hang on our Christmas tree. As a child he told me of the tradition of good luck they bring.
Yesterday, through the lovely blog Chronicles of a Country Girl , I learned of a Flikr group called 1000 Cranes for Japan, a simple way to show support for it's people. In addition, The Miya Company is donating $5 for every image of a paper crane it receives up to $5000 to Save the Children Japan.

Also, Students Rebuild is collecting 100,000 actual cranes. They will be woven into a sculpture and the Bezos Family Foundaiton has pledged $2/crane up to $200,000. The money will be used by Architects for Humaity's rebuilding efforts in Japan.See this link for more information: Students Rebuild
If you would like to participate, I have created a paper crane tutorial found here: Origami Paper Crane Tutorial
