Surely no one would mind bumping into the other person if they fortuitously found their Mr. Right or Ms. Right. But who knows whether or not the God is playing a trick on you? So my suggestion is: you should be careful enough when rushing around the corner, or simply pay attention to the Corner’s Communication Warning Sign. Designed by Sanghoon Lee, the corner sign could sense the sound emitted by someone approaching around and then light up to warn the other guys. That’s especially ideal for public places like the hospitals, restaurants and offices, where a large number of people walk around frequently.
