This extension displays your positive affirmations or inspirational images at a rate that the eye can't really catch, but your subconcious mind can.
It is completely non obtrusive, you will only see a flash with either your images or your affirmations while you are browsing.
It asks you to register so that you can use it in any computer that you use. Just log in and your affirmations will be downloaded to the computer you are using. Log out if you are sharing the computer and you don't want the next person using it to recieve your subliminal messages.
