What you're seeing is post-process effects. Basically they first render the scene into a framebuffer object (FBO), then take that as a source texture and perform various operations on it. Among other things they talk about bloom effects etc, which are done in the same manner. |

The smoky trailing effects are likely implemented with a particle system. |
