Popularized by Inception, lucid dreaming is still considered to be a work of fiction that no one can truly achive. I want to just help those who want to help themselves to enjoy this sort of perfected virtual reality within themselves. There are communities of lucid dreamers that get together and talk about techniques and ways to achive them, I will share what tricks I did when first starting out.
So I posted an android app on the market called Amazing Honks Professional and its reached the 100-500 download threshhold as well as many 5 ratings. While its not really a secret as to what the app does (it honks), it has a randomization script in it so the user can hear different pitches and a secret song for users who really enjoy it.
