GoodBrainWave is run by Will Williams, a subconscious psychologist, hypnotherapist, and graduate of psychology and neuroscience. My personal site is here. I am fascinated by various channels of influence - not only how we influence ourselves through thoughts and perceptions but also how our minds influence our bodies. The advances of neuroscience, brainwaves and mind-mapping have really opened up a pandoras box of intrigue in terms of where our thoughts and feelings come from.
The brainwave entrainment CDs are a great blend of technology and research, engineered into a very convenient format for regular and easy use. People report all kinds of results and effects, and its a delight to be a part of anyone's meditative explorations.
