Sonar Those wacky military scientists are always coming up with neat stuff. The latest - you can turn your tongue into a sonar or light sensing organ. With a little computer augmentation, you can use sound waves to find your way about a dark room, or receive radio signals that will let you sense an environment without any light. How would your life be different if you had an ability to detect objects by sonar? Would you sign up to get this new gadget?
