Just came across this project, via Project Gutenberg. It's a Kickstarter that's not just for entertainment!

Library For All is attempting to create a digital library of educational materials for the developing world. They're helping to build physical schools which will have internet access and cheap tablet e-readers. The idea is to level the playing field (or at least move towards a more level playing field). To give kids up-to-date and clearly legible textbooks, access to stories and creative works, and a hands-on understanding of technologies many of us take for granted.

Oh, and pledges are tax deductible.
