The interesting thing about the Ritot is that it doesn't have any kind of display to show you the time or notifications. Instead, the Ritot projects your notifications directly onto the back of your hand. When you shake your wrist, it will display the time, and when hooked up to your smartphone, it can also display call info, text messages, reminders, Twitter alerts and more. Each notification will show for 10 seconds, and you can change the projection between 20 different colors.
