I had been using a trial version of G-Force and decided to purchase G-Force Gold because it is the best visualization package I have ever seen. It is better than the Electric Sheep screen saver, and I believed that to be impossible. The number of visualization combinations offered is simply incredible. It puts you into a trance-like state, mesmerizing and tempting fate as the visualizations dance to sound of the beat of the music. Thanks guys for doing such a terrific job.
