Bumper stickers have long since been a way of communicating your thoughts, feelings, and opinions about the state of the world in a very public manner. You can cheer on a politician, encourage people to smile, or give warning that others are too close behind your car for your liking, all from a paper sticker on your bumper. The problem with this form of communication is that the sticker is going to fade from exposure to the elements, and your opinion on the content of the sticker might one day change.
If you like to spice up what you want the world to see on your vehicle, you could always get the Talelight Electronic Bumper Sticker. This is a full-color LCD screen that was made to survive being attached to the back of your car, and is powered from any standard 5V USB power source. That being said, it comes with a 15′ long cable so it can reach the cigarette lighter inside of your car.
This only shows static images, and has the space to store up to 25 pictures, of which it can play in any order of your choosing. The images being displayed are 1280 x 320 pixels, and can be created in any program. It’s not cheap at around $135 after shipping, but it will let you show anything you think is worth flashing to everyone else on the road. Now if only it could play movies so you could pull it in the car for entertainment on long trips.
