Change windows start screen to something more interactive?

Would it be possible to change the Windows desktop and turn it into something more like a game? Something like running a program that would have access to the files in the computer and display the desktop as a 3D plane with the icons accessible by clicking? I don’t want to create a brand new OS, just attaching some kind of program onto it.

If so, which language would be best suited for this?

And are there any tutorials around? Also, is this even feasible, or just plain not possible?

I have not been able to find anything so far but I am willing to learn any language necessary.
