Experiment : Real-Time Pixel Processing : Smoke
A 3-by-3 neighborhood blur filter. This means that each pixel looks at its (eight) surrounding pixels. The color values of those pixels are used to calculate the average color. You can create the illusion that the image is moving sideways by taking a little more from the color of the pixel on the one side than on the other side. When you calculate and draw every pixel in the image this way you have created a blur filter.
