Earlier this year, Sony introduced a line of green concept gadgets, called ODO, which get their power from alternative sources such as solar panels and mechanical cranks. The newest addition to the ODO line is this Twirl N' Take digital camera. Fifteen seconds or rolling provides enough juice for one photo. I like that they chose to go with rolling over a hand crank. It seems much less tedious. The rolling approach also lead to an interesting form which also creates a natural view finder and handle. Very cool concept. (Found through Apartment Therapy Re-Nest).
