For last month's MineCon, Mojang asked video team Hat Films to whip up a video that chronicled Minecraft's development over the past couple of years. Hat Films has had this up on its YouTube page for some weeks, but I didn't catch the video until Mojang mirrored it.
I myself have yet to play Minecraft, so this short gave me some insight into the many features of the game and how they were gradually introduced to result in the full release version. I'd like to get into it some day, put I always tend to jump on these kinds of things when everyone else has grown sick of 'em.
