When I was a child, to see the textbook written, sunflower will follow the sun, the sun will go, so there will be a child running to watch, and now, if you go to the field to see is certainly a torture. Japan's Kyushu University developed the machine with sunflower, infrared sensing function, will follow your direction and say hello, central flowers was built by LED light, when you are waving to it, it will shine its light LED to say hello to you.
