If there's one thing we love, it's optical illusions. They're a fantastic reminder of how the way you perceive the world isn't objective — it's influenced by everything from the biology of your eyes to the way your brain processes images. The Best Illusion of the Year Contest celebrates the world's greatest visual deceptions, and they've just announced the top 10 finalists for 2018.

The Worm's Eye View Illusion – Michael Pickard and Gurpreet Singh, U.K.
The only thing changing in this image is the colors of the worm's stripes. You automatically see the bolder color as the foreground and the lighter color as the background, which creates the illusion of movement.
Triply Ambiguous Object – Kokichi Sugihara, Japan
This two-dimensional image placed on a horizontal surface appears as three different three-dimensional structures.
Danswing Papers – Takahiro Kawabe, Japan
Simply by changing the background color, you can make static shapes appear to shift position slightly.
Movement Illusion With a Twist – David Phillips, Priscilla Heard, and Christopher Tyler, U.K.
This demonstrates two different movement illusions. In the first, adding a background makes a simple diagonally flowing ribbon appear to move to the right. In the second, two opposing expanding and contracting ribbons make the shape appear to twist.
The Squish Squash Illusion – Stuart Anstis and Patrick Cavanagh, U.S.A. and Canada
When you flash an object on or near a moving texture, it appears to change position or shape.
