Mojang, the Indie Game studio behind Minecraft, is coding video games to raise money for charity. They are working along with some other Indie Game studios such as:  Grapefrukt, Ludosity, Oxeye Game Studio, Vlambeer, and Wolfire Games. The studios’ work will be livestreamed for the next 78 hours as an event known as Mojam 2 (aka: Mojam 2013).

As the official Mojam site states, you can use their form to pay as much as you want to support two charities, while watching the amazing in-game-creating-process. The two charities that you’d be helping to support are Electric Frontier Foundation (EFF for short) and Block by Block (which is run by Mojang and UN-Habitat), so you know your money is going to a good cause.
Another fun and amazing part to this fund raiser is that the viewers get a say in the themes of the games being made; So far the themes for Mojam 2013 are..
