I live in Hawaii, so even if you know nothing else about origami, chances are you've made at least one origami crane in your life.
There's a tradition that if you make a 1,000 cranes, you get a wish. I went to a graduation party once, where 1,000 cranes were scattered around the tables to be unfolded later to make a wish for the graduate's mother (whose health wasn't good).
It was interesting to think of creating a wish by effort, by doing work, which built up the hope. It was a nice thought.
Therefore, below are the details for Students Rebuild, which is working with DoSomething.org to send aid/donations to Japan.
Make as many cranes as you can, take a picture and email it to Students Rebuild, then send the cranes themselves. They're looking for a total of 100,000, which will result in a $200,000 donation from Bezos Family Foundation.
In their words:
"Help Japan by making paper cranes. These simple yet powerful gestures will trigger a $200,000 donation from the Bezos Family Foundation - $2 for each crane received - to Architecture for Humanity's reconstruction efforts in Japan. Once we reach our goal of 100,000 submissions, the cranes will be woven into an art installation - a symbolic gift from students around the globe to Japanese youth.
Questions? Email us at email@example.com"
And a breakdown of the steps:
"1. Make a paper crane (watch a how-to video)
2. Snap a photo and upload it, along with a message of support to the Facebook page "Paper Cranes for Japan."
3. Turn your crane into dollars for reconstruction - and eventually an art installation - by mailing it to us. Or, team up with friends and fold as many as you can! Email us to receive a pre-paid shipping label for large boxes (over 50 cranes please).

So get together with friends, have fun, and build a little hope with some time and effort.
