At last, a USB peripheral that actually makes sense! As I sit in front of my desk, rubbing my tired eyes after a long day starring at a computer screen, I can see the need for the USB Vision and Posture Reminder, which has a very simple function: it blinks a blue LED if you're sitting too close to your monitor (35 cm/13.7 inches), reminding you to back up, saving your eyes and correcting your posture. No word on whether or not it also includes a recording of your mother's voice telling you to sit up straight.
