New generation of Save icon that is not a "disk"?

Currently, the save icon in almost all applications represents a 3.5-inch disk from the 20th century. An example from Microsoft Office 2010 is shown below: As we move towards more advanced technology, this "disk" save icon now seems obsolete. Kids born in 21st century might not even know what a disk is. Is there any good alternative save icon out there that can replace this "disk" save icon in app
