Question Mark ships motion-sensitive speaker

Question Mark Entertainment announced on Friday the release of its new Motion Speaker. The single-piece audio system avoids traditional dials in favor of motion-sensitive controls: listeners change the volume or tune different radio stations by passing a hand in front of the relevant sensor. An auto-scanning FM receiver saves the user an element of effort, Question Mark says. Designed as a fashion piece, the Motion Speaker also has a built-in ambient lighting system and is meant to be used with virtually any power source: it can be powered through traditional AC power, four AA batteries, or a computer's USB port. The speaker works as an audio device for any Mac, Windows PC, or portable audio player with a minijack connection and will ship next week to Europe for €80 ($103).
