Script em Pygtk que baixa uma imagem do globo do site http://die.net mostrando onde está noite e onde está dia.

O script cria um ícone na bandeja para poder controlá-lo com opções como atualizar, parar, escolher a projeção e encerrar.

As escolhas de projeção são:

- Peters ( http://static.die.net/earth/peters/1600.jpg )
- Mollweide ( http://static.die.net/earth/mollweide/1600.jpg )
- Hemisfério ( http://static.die.net/earth/hemisphere/1600.jpg )
