Douglas Saldanha, a landscape architect from Mumbai's Worli, in memory of his late sister Twila decorated a 67-feet Christmas tree with over 50,000 lights, out of which 192 smart lights can be voice-controlled with Alexa.

The setup is made magical by Alexa, a voice assistant that comes with Amazon Echo smart speakers. Visitors on a mere command to Alexa can change the colour of these smart lights to match their favourite, example "Alexa, change magic tree to pink".

Alexa at its best!

Douglas's garden at Adarsh Nagar, Worli is open to public till January. He has even arranged for a photo booth for those who want to click a picture with the Alexa powered Christmas tree.

He is also organising three parties, one that was just held on the December for 145 underprivileged kids where he got eminent political leaders to gift educational accessories like school bags with exercise books and compass boxes.

On the December 28 Douglas is hosting a children's Christmas party and on January 2 a New Year's party for senior citizens of his colony.
