Today I have another trick for you that displays cool graphics on the iTunes Visualizer when playing songs in iTunes! This trick only takes one easy step. Open iTunes and start playing your favorite song. Then click command + T (and if you want it full screen just click command + F). The graphics will change with the beat of the song. To access the iTunes Visualizer from the toolbar, go to view then down to show visualizer. You can also customize the Visualizer by choosing different kinds of Visualizers like the Itunes Classic or Jelly. To do this you go back up to view in your toolbar and scroll down to Visualizer not View Visualizer. After that select the kind of Visualizer you would like to view.
