Now here’s a bright idea. How about an intelligently designed back pack equipped for cyclists in mind. Designed by Lee Myung Su Design Lab and going by the name of SEIL Bag. Made for cyclists in mind the SEIL bag utilizes an LED Display (flexible PCB) on the exterior. The bag is equipped with two separate modes – driving mode and emotion mode. Driving mode, shows left and right turn signals while emotion mode utilizes random emoticons used just for fun!
