The display is a 50 x 50 2D white LED matrix, that spins at about 4Hz (250 RPM), creating a persistence of vision (POV) effect. A point cloud of voxels (volume elements) can be animated in the display by sending them to the display at 12 to 20 FPS (frames per second). The virtual 3D space is drawn as a bunch of slices: as the LED matrix spins, Swimming in Data, displays the correct slice at the correct time 90 to 120 slices.

The 50 x 50 x 100 = 250,000 voxels, are binary, with no grey scale levels, although the ones near the centre appear brighter as they are moving slowly and more dense.
