- Drones traced weird patterns in the London sky on Wednesday for no clear reason.
- At one point they formed into a QR code linking to the site of an insurance company.
- Such QR codes are not a regular sight, but have been deployed before in China.

The code appeared to be formed of several hundred drones, which arranged themselves into a few shapes before settling into a large, scannable image, which hovered for around 20 seconds.
