Minecraft: The Story of Mojang is a documentary currently under development by 2 Player Productions. They put together a 20 minute short about Minecraft for all to view online, but want to expand it to a feature length presentation. For this, they have turned to Kickstarter to try and get donations for the project.
To sweeten the deal they have now listed some of the stuff that comes with being a very gracious donator. While even at $1 there is access to the development blog, the cool stuff really shows up once someone really digs into their pockets.
