The idea was inspired by two innovations: a chair which senses farts and automatically posts a Twitter update with each fart, and a remote that randomly changes channels based on brainwaves. The step-by-step instructions for creating your own fart-operated remote are online at the Instructables website.
Implications - The methane sensors allow the remote to detect when you have farted; when you do so a signal is sent and random TV channel will appear on screen. This is a humorous and interesting project that turns a fart into something of value. Nifty idea, that is for sure.
