The touch screen that Jeff Han created is amazing. You can click and drag, resize and all that good stuff.

William Kamkwamba

This guy, William Kamkwamba, is what you may call a child prodigy. When he was at the age of 14 years old he created an electric out of a bicycle and some pipes and house hold items just from reading a book. Since then he has been able to create light bulbs and radios.
