Here is a totally cool backpack that goes by the name of SEIL Bag. It’s a backpack meant for cyclists and features an LED Display (flexible PCB) on its face. 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 for the rider, which is controlled via a detachable controller. This makes it easy for the following traffic to know the riders intent. The cool-quotient is upped with the Emotion Mode; here you can display a variety of emoticons, just for the heck of it.
The bag also displays brake signal, cruse signal and emergency signal; the acceleration sensor detects speed and turns on stop signal automatically. The signals can be controlled intuitively; pushing the lever up, turns on left turn signal and vice versa.
A very classy bag with a lot of use, I really dig the emoticon aspect!
