Biome by Samuel Wilkinson is a flora terrarium that can be controlled through your smartphone or tablet.
From Design Milk:
Similar to a living Tamagotchi, you can control the Biome’s climate, water level and nutrients. According to the designer, “the idea promotes ‘digital downtime’ by finding an alternative use for smartphones and encouraging their owners to consider a slower life. The control and nurturing of a real mini eco-system takes patience and care, contrasting with the immediacy of messaging or tweeting that is so characteristic of the smartphone generation.”
