Botanicalls, a service dreamed up by some folks at New York University’s Interactive Telecommunications Program, first devised a way to get your plants call you when it’s time to water them.
According to a post on WebWare, those same folks have now advanced the service to interact with your Twitter account. So, instead of calling you, the plant can now send you a Twitter post to let you when it’s thirsty. Oh, it will also send a note of thanks once you’ve given it a drink.
