'Expose' repurposed for window minimization

Hi elementary OS

Now that you have disallowed icons on the desktop, I have a suggestion for how to use that desktop space:

Whenever a window is minimized, instead of "disappearing", a screenshot (or rather, a 'windowshot') is taken, reduced in size (say, about 50%) and "planted" on the desktop. If a second window is minimized, it gets the same treatment. If necessary, the windowshots are reduced in size and/or moved around in order to accommodate the new windowshot.

Ubuntu and Mac has a similar feature ('expose'), but in their case, one has to click a certain key combination to make it show. elementary OS has the opportunity to show it permanently :)

I think this way of interpreting the concept "minimize" is quite intuitive, at least compared with the competing ways of handling minimization.

What do you think?

EDIT:
I don't think this concept of minimize will interfere with your current consensus on the meaning of closing a window. I remember reading a discussion where minimization was criticised for being too similar to the 'close'-function to justify it. I don't think this issue applies for this alternative interpretation of minimize. Would you agree?

EDIT 2:
