QR code made of 130,000 trees can be scanned from the sky

QR codes might have had their day in the UK, but in China they are insanely popular and used by everyone – from big retailers to buskers – for things like information and even payment.

So it’s pretty cool that Xilinshui village in Hebei has used 130,000 Chinese juniper trees to create, what I assume, is the biggest QR code ever.

The code measures 227m (744 ft) along each side and is designed to be scanned by passengers as they fly over on planes travelling to Beijing. The trees range from 80cm to 2.5 metres in height so the code can actually be scanned.

After scanning, the code takes you to Xilinshui’s official tourism page on WeChat, China’s biggest messaging app.

Whatever your personal feelings about QR codes, this is pretty awesome. The precision and planning behind this stunt is nothing short of amazing, and I love that the code actually works. With all the coverage generated, people may also be able to scan the code from images, so the stunt has an even wider reach than perhaps intended. Big thumbs up from me on this on.
