How Computers Work (and Play) With Pictures
Think of the grid on the right as a simplified view of a black-and-white computer screen. Each grid square represents a pixel. Naturally, they're much bigger than the real thing. Doing this activity will show you how an image can be portrayed with just two instructions: on and off.
Darken every pixel that is supposed to be off by clicking the squares with a "0" in them. Don't click any of the squares with a "1" in them—they represent pixels that are on. When you're finished, be ready for a small surprise.
