Scout writes, "Billions of people experience a severely-censored version of the Internet -- most famously in countries like China and Iran. Now there's something you can do about it."
Lantern is an open-source, peer-to-peer tool that helps people work around this censorship by crowdsourcing access from people in other countries. Run it in "give" mode to help people elsewhere in the world access blocked sites. Run it in "get" mode to escape censorship.
The Lantern folks are running an Indiegogo campaign too. One of the perks? A "Lantern Pi" -- a Raspberry Pi board that runs Lantern in "give" mode, inside an actual lantern, shining brighter as more traffic passes through it.
