It says right there in the description - Enjoy the concept that I made? .
This is an artistic rendition of what Windows 12 might look like and not the actual product.
I like how this artistic concept still includes animations on Windows logo freezing up during the boot process. It's such a staple of Windows at this point!
You forgot to include the pretty UI failing to respond or the UI host process crashing silently for no discernible reason, forcing you to manually restart explorer.exe. Windows 8 "metro" UI was actually great at being smooth, responsive, and stable.
