Measuring 10 meters tall in non-freedom units, this Lego Christmas tree is thought to be the biggest of its kind in the world. It's composed of over 600,000 bricks, has a thousand baubles dangling from its 172 branches, and is now lit up by a classic garland of LED lights. After two months of construction, it has been unveiled to the public in St Pancras International Station this week, and even the typically jaded Londoners are finding themselves wowed by its blocky intricacy.

Among the decorations is a cube with a QR code for more information and there's some related treasure hunt competition, though we didn't bother to look into it. Now excuse us while we, er, do something other than hunt for said treasure.
