The award-winning SEIL bag by Lee Myung Su has an LED display and a remote control for your handlebars.
The bag is designed to work in two modes: Driving Mode and Emotion Mode. In the Driving Mode it shows left and right turn signals, brake, cruise and emergency signals, controlled via a detachable remote. An acceleration sensor detects speed and activates the stop signal automatically. Emotion Mode displays a variety of emoticons, just for the heck of it.
The promo video is great, but the music will actually make you hate the product. Hatred is also an emotion.
