Among the most annoying type of people are those who park in disabled parking spaces when they don’t need to. The Russian organisation Dislife has come up with an ingenious way to make them think twice.

The sign painted onto the tarmac of disabled parking space is pretty easy to ignore, if you’re that way inclined. So they’ve developed a hologram that emerges when a car without a disabled permit edges into a restricted parking spot.

It works through dispersing a thin layer of air saturated with water. A moving image of a person in a wheelchair is then projected onto this layer to create the perception of a three-dimensional hologram to confront the driver. The moving image also comes accompanied with sound, which announces statements such as “Stop! What are you doing? I’m not just a sign on the ground.”
