From Imperial Penguin:
Digital Highs is the desktop port of our successful iPhone and iPad app by the same name. Binaural beat based mind altering programs are becoming increasingly popular. Digital Highs takes the experience to a new level by combining the pulsing beats of binaural entrainment with flashing lights. What you should expect from Digital Highs is a type of intense meditation. Terms such as hallucinogenic and psychedelic are still used because those are terms that the average person can relate to a little better, but in reality the "hallucinations" will seem more like vivid daydreams. Like any mental feat, the daydreams and clarity of consciousness won't come easy to beginners. For that reason it is suggested that everyone start with the sessions labelled "beginners" in their description. These are designed to be easier for people less accustomed to meditation and other mental visualization type exercises to benefit from. The desktop version features additional ambient sounds that may be more pleasing to the ear than pink noise, and a secondary backing tone that may further aid in meditation.
