A town in Iceland has employed the use of a startling optical illusion as a way to improve road safety.
The small fishing village of Ísafjörur painted the 3D pedestrian crossing in an attempt to slow traffic on a narrow street.
Drivers who pull up to the crossing will see the amazing sight of pedestrians appearing to walk on air as the move from one side to the other.
Environmental commissioner Ralf Trylla came up with the idea after seeing a similar project in New Delhi, India.
But how does the amazing creation actually work?
The optical illusion shifts depending the perspective it is being viewed from.
From the air, the white stripes jump up, making them appear as a column of walls.
At ground level, the bars seem to hover just above the ground.
The paint gradients make it appear as if the bars are floating above ground, and tricks the brain into thinking they are not on the road.
Even the sight of someone walking across them doesn’t make the white bars appear flat.
For now the project is an experiment as the town waits to see how effective it is in curbing speeding.
If it works, more will be rolled to other areas of the village.
Another optical illusion is also sweeping the web at the moment – and the tricky colour-based quiz will strech your eyesight.
The quiz appears simple at first, and shows 40 equal sized squares lined up together.
Each square appears to be the same colour, but in fact one of the 40 is a slightly different tone to the rest.
The quiz requires users to identify which square is the odd one out, and then colour match it to four options given at the bottom of the page.
