Scientists in Kamakura have developed a botanical interface which allows plants to post their "thoughts" online. Apparently, bioelectric currents traveling along the plant's leaves change depending upon what's happening around the plant. Temperature, humidity, vibrations, people nearby, etc. all impact how the plant is feeling. An algorithm was developed to translate those feelings into Japanese sentences.
The first blogging plant is named Midori-san. Visitors can give her a dose of fluorescent light (for which she will promptly thank you). A more complete description of the experiment can found here. Midori herself and her blog can be seen here.
No word yet when they'll turn the comments field on because I disagree with a lot of what Midori-san is writing (especially about greenhouse gases).
