Mind Supplies
Audio-Visual Library for Bio- and Neurofeedback
Here you can download low resolution samples of each of the three series in each of the 14 categories. These are each about 4 Mb and will take a while to load. All puzzles come in a version to load on to your hard drive and they are also supplied on DVD in case that is more convenient.
