Max Erdenberger for W+K Studio designed this poster to raise relief funds for the devastating earthquake and subsequent massive tsunami that struck Japan March 11, 2011. This is a good design and a good way to turn simple things in meaningful things.

Another interesting way to help Japan is donating to the American Red Cross using the Apple iTunes Payment system. Apple setup a dedicated page to raise funds, and all the money (100%) of the donations will go straight to the American Red Cross. That’s good, and really simple with the one-click payment system (for iTunes users obviously).
