You will see a photo of a road scene for a brief amount of time, followed by the same photo where something has changed. Between each image there will be a blank screen that mimics an eye blink.

The photos are on a loop. You will see one after the other continuously for about 6 seconds. There will be a break for you to identify the change... if you spotted it! You can either click where you think the change was or click 'Show the change' if you missed it.

 Good luck!
