Open Source Ecology is a Kickstarter project worth donating to. They’ve reached their goal, but if you’ve ever wanted to be able to make your own tractor in twelve hours, it’s worth helping them go above and beyond.
From their site:
The aim of the GVCS is to lower the barriers to entry into farming, building, and manufacturing. Its (sic) a life-size lego set that can create entire economies, whether in rural Missouri, where the project was founded, or in the developing world.
