Created by Almap BBDO, Greenpeace Brazil has launched a campaign called “Black Pixel Project.”

On the website, users are asked to install a program that opens a small black pixel over all the windows on their monitors. Since users are able to see how many people are saving energy with this downloaded program, the main purpose of “Black Pixel Project” is to show that with each pixel installed, a few watts are saved.

Unfortunately, this website feature can only work with CRT (Tube), and on plasma monitors.
