Botanicalls - plants and humans communicate

Botanicalls was developed to provide a new way for plants and people to communicate in order to develop better, longer-lasting relationships between them. Instead of using an automatic watering system or developing methods for plants to text or email people, the Botanicalls team has created the means for a more personal relationship. Each plant has a unique voice based on its botanical characteristics, and each has the ability to tell people when they are in need of assistance. They're also polite: they make sure to call and say thank you when they get a good watering.

The communication is done via Botanicalls Twitter, which answers the question: What's up with your plant? It offers a connection to your plant via online Twitter status updates that reach you anywhere in the world. When your plant needs water, it will post to let you know, and send its thanks when you show it love.
