Does anyone know the site where you make a brick for a virtual building for a celebrity or pet memorial, etc?

I used to go to a site that has virtual buildings. You can start your own building or add to an existing one. They have them for celebrities - we made one for Bo Bice. They have them where you can add your pets who have died to a memorial building. It's a really neat place. When my computer died I lost the address. Can't find it no matter how I have searched. Any help would be great. Thanks!
