A giant 90ft twinkling Twitter Christmas tree towers over passengers at the newly opened Queen's terminal at Heathrow.
The largest interactive tree in London which comes to life as passengers tweet a festive greeting using the hashtag #T2Christmas, can be found at Terminal 2 - The Queen's Terminal.
Heathrow has created and installed a chirpy vinyl tree, with a vintage touch, reminiscent of the type The Queen would have enjoyed as a child, thanks to Fisher Productions.
It is complete with a replica of her iconic coronation crown which sits at the top of the tree and has lights draped around it which can be triggered to twinkle and sway as soon as someone tweets.
Normand Boivin, Heathrow’s COO said: “Launching the Terminal 2 Christmas tree with the first tweet was brilliant fun.
"It is a fantastic piece of technology and really adds a festive touch to the terminal.
"We’re certain our passengers will enjoy taking part in lighting up the tree and look forward to hearing their thoughts through Twitter."
The tree will remain until January 6, the twelve night of Christmas, allowing hundreds of thousands of passengers to enjoy it.
