A big pearl with an avatar is a pearltree. It behaves like a folder of pearls: you can open it, close it and move it into other pearltrees. Create pearltrees and fill them with pearls to organize your account!

Every pearltree has a detail window that displays more info about its owner and its content. You can copy or move a pearltree, or share it whether on Twitter, over Facebook, by mail or on your blog.
