This demo implements a simple light trail technique. The light sources are rendered into a texture. This texture is then blurred and scaled down slightly between each frame and new light rendered into it the next frame. This creates a corona around the light and a light trail as the light moves or the view position changes.

This demo should run on Radeon 9500+ and up and GFFX 5200 and up.
