The blooming gadget connects wirelessly to the home’s electricity meter and changes colour and shape depending on the amount of electricity used.

When electricity use is low the flower glows a healthy greenish-blue and stands tall and open.

But as more lights and electrical appliances are turned on the flower closes up and turns red.

If energy use remains high, the flower wilts and turns a deep purple before ‘dying’ – or going out.

The Wilting Flower is a prototype for now, but is expected to sell for around $90 if it gets to market.
