Recently BludgaBoy has shared a LittleBigPlanet 2 PS3 BETA - Windows: LBP Edition Creation video showcasing the work of Boss_Mob, SaggySackBoy, tomatenbrei and daFRED94.
While the game isn't available until later this month, those interested can check it out below.
To quote from Kotaku: "This Windows XP homage, built in the LittleBigPlanet 2 beta, won't run a copy of Excel or PowerPoint, but it does do a reasonably good impersonation of the operating system's desktop, start menu, built-in timewaster games and, naturally, a blue screen of death."
Finally, from the video's caption: "It works... well, *almost* perfectly (just like the real Windows, there are some kinks in the works), and it's an extremely accurate re-creation, right down to the log in noise. You've got pictures, music, videos; even some built in games for you to play! Who needs the NT kernel or C++ when you've got LittleBigPlanet 2?"
