I thought this was interesting: Future Edisons - on PBS Answered
Everybody has a great idea that could change the way we work, the way we live or the way we play. Everyday Edisons documents the development process of 12 inventions and the parallel stories of the people who invented them. Selected from thousands, the 15 Everyday Edisons learn how their extraordinary ideas are taken from a sketch on a napkin to a store shelf.
Take Sheldon Levinson and Michael Diep: both like to tinker with concepts for new and improved products, or simply the next crazy fad. Levinson, a true kid-at-heart, is always looking for the next best toy or gadget to make people smile. Taking the traditional favorite bubbles and combining them with the lava lamp, another iconic American gadget, he developed the latest twist on bubble toys.
Diep, a refugee from Vietnam, has thousands of inventions in his back pocket, one of which is a new design for a dual cat toy and claw scratcher. As a hectic business consultant, Diep encountered a challenge many of us face lack of time. With limited personal free time, much less time to take his cat to the veterinarian for nail trimmings, Diep incorporated sand paper into his jungle gym to naturally file the nails as it played.
Inventing isn't just for adults, the retired or the self-proclaimed inventor. Mark and Cody Fox, brothers and juniors in high school, were tired of paying year-end fines for bent corners and broken spines on their school text books. After combining a few fabric swatches, some hot glue and pieces of plastic, the young men developed a way to prevent the dreaded fines come June.
