Remember those silly plastic flowers that danced? Well, here’s the next inevitable step: a Japanese inventor has developed a device that can be buried in a plant pot and uses vibration to cause the leaves of plant therein to oscillate as speakers.
Grow your own speakers. Yay.
Personally, I’d have far too much fun burying such a device under a friend’s vegetable patch, on a long (buried or otherwise concealed) cable, and have his plants ‘talk back’ to him when he talks to them. Where can I get one?
