The Holocaust Museum in Houston is doing an amazing thing. They have set up a goal to collect 1.5 million handmade butterflies (in any form, painting, collage, sketch etc.) from around the world by December 31st, 2012. Each butterfly represents one of the 1.5 million children who perished in the Holocaust. In the Spring of 2014 an exhibit will be installed in the museum to serve as a memory of the children.

The butterflies will eventually comprise a breath-taking exhibition, currently scheduled for Spring 2014, for all to remember. The Museum has already collected an estimated 900,000 butterflies.
