More Fusion 8 effects. This is using the particle engine and the "Replicate 3d" node. Basically the distribution and spin of the cubes is controlled by the particle engine then replicate3d places another 3d object (in the case a cube) at each of the particle points. Using the OpenGL renderer allows depth of field (As far as I can tell that's not available with the software render) and a slight blur to finish.
