Design of useful things - Manu Prakash: A 50-cent microscope that folds like origami

Perhaps you've punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could revolutionize healthcare in developing countries ... and turn almost anything into a fun, hands-on science experiment.
