Have you ever wanted to know what's inside an ambulance, a fire engine or a police car?
Well, your wish has come true thanks to the Tetris Challenge - an emergency service craze.
Emergency service workers around the world are sharing the contents of their work vehicles, often lying down next to them, so they resemble a screenshot from the popular video game.
It started when the Zurich Police department put on their Facebook page : "If you have always wanted to know what is all in a patrol car of the traffic - here you go. We wish you a #happy Sunday
#KantonspolizeiZurich"
The arrangement won the police department thousands of likes and shares and 670 comments.
The photograph was taken during a department open day, with two officers joining in and a drone capturing the image.
Other Swiss emergency response teams also got involved, such as the Thusis fire department, who joined in the Tetris Challenge.
There were rescue services, fire departments, other police departments and private companies all joining the challenge.
From there, it spread to the Netherlands, Hungary, Austria and Germany.
And it went east, with Singapore's civil defence force posting a gallery of the Tetris Challenge, too.
As did first responders in Mexico and Taiwan. The idea may have emanated in New Zealand, where a police department had created a near identical tweet last year, which they reprised again for 2019.
