Making video games is an incredibly length, detailed and technical process. It would be impossible to visualise all the code that goes into one without being some kind of omnipotent being. Unless you're watching this video.
Put together by LittleBigPlanet developers Media Molecule, this is a "code swarm", a graphical representation of the work of the game's programmers, artists and designers.
And it shows the creation and finalisation of LittleBigPlanet 2.
Every little sackboy you see floating around on the screen is a Media Molecule staffer. And all the points of light around them are files created or edited by each person during the process of developing the game. All the moving around is the result of the developers sending and editing each other's work.
You'll also see files come and go as they're created and deleted.
