I saw this on the jumbosandbox blog and really like what they are trying to do.  They have set up a relief project for Japan, in addition to your donation they will send you a sticker. I will be sending my $5 off soon!  You should do the same.

Here is the original post on their blog for convenience as it has all of the information.
