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 applications? Or, probably we can design a new save icon here and make it a standard? Ideally, the icon should not represent any hardware, because it will become obsolete again as technology evolves.
Very IMPORTANT Note:
This question is NOT to discuss whether we should change the "disk" save icon or not. I know the icon is still perfectly OK and friendly to the end users. There are questions on Stack Overflow and ui.stackexchange.com that discuss this.
I just want to look for good "save" icon that does not look like a disk (or hardware). Just take this question as a brainstorming or a design challenge. :)
At least one save icon image per answer please.
