Fido Fashions' Power-Generating Dog Leash adds some much-needed design to this usually boring product category; the device features on-board storage for waste bags and an array of three LED lights for night walks. The cool part is that the LEDs are battery-free--they're powered by the coil and recoil of the leash.

Product Design & Development's "Inside Design" section has an interview up with Andrew Goddard of Goddard Technologies, the industrial design firm behind the leash. Check it out here.
