Heres some interesting reading. Its got pictures for you over active ADD types



Astral travel, and other occult abilities, are closely associated with the development of the 'light in the head'. After physical relaxation, concentration upon the pineal gland is achieved by staring at a point in the middle of the forehead. Without straining the muscles of the eye, this will activate the pineal gland and the 'third eye'. Beginning with the withdrawal of the senses and the physical consciousness, the consciousness is centered in the region of the pineal gland. The perceptive faculty and the point of realization are centralized in the area between the middle of the forehead and the pineal gland. The trick is to visualize, very intently, the subtle body escaping through the trap door of the brain. A popping sound may occur at the time separation of the astral body in the area of the pineal gland.

edit: interestingly enough, in shamanism the Penguin is strongly associated with astral travel --> http://www.geocities.com/~animalspirits/index14.html
