This one took a while to figure out. A Matrix-style wall of text shows the flux values in progressive velocity channels through a data cube. Both the position of each text object and its value (scrambled slightly to give a more Matrixy-look) are derived from the data. Most of the data is noise, but the brightest regions correspond to galaxies detected in neutral hydrogen. These data values are shown as persistent text objects at a position corresponding to their velocity channel, and are sampled more fully than the rest of the noise. Also there are various reflecting planes at work to make it look cool.
