What we love about the USB-fixated folks at Brando is that along with some pretty nutty items, they also sell some pretty useful stuff as well. Consider the Visomate, which helps you reduce neck and eye strain while at the computer. The innocuous-looking disc is placed on top of your monitor, plugged into a USB port, and using an “ultrasonic sensor” helps you determine the proper way to sit if front of your monitor. LED lights and help you position yourself, for ergonomic goodness: Blue means “Not Recommended”, while Red means “Too Far”. Pretty helpful, and great for both kids and adults.  The Visomate is available for $26 USD.
