Yahoo News reports "People who like talking to their plants can now enjoy a musical accompaniment, thanks to a Japanese invention that turns petals and leaves into speakers. Several others are also reporting details of how it works." http://story.news.yahoo.com/news?tmp..._japan_flowers
Called the "Flower Speaker Amplifiers", music is sent from a vase at just the right frequency and vibrates up the stems and then converted into audible sound by the plant as a whole.
Imagine plugging GPO into your houseplants!
Now you can really veg out and listen to music.
