For the traffic geek....

Link for more info: LED Traffic Light USB 2.0 Hub

In addition to being a 4-port USB 2.0 hub, this little gizmo also records and plays back up to 10 seconds of speech to store a reminder or memo. Turn your traffic lights to red when you want to be left alone, green when you feel sociable, or amber when you want to procrastinate. It also has a handy clip-on top to store a message or two.
