This time I'd like to show you an amazing optical illusion I've recently found.
Here's the link to it: CLICK ME!
First, take a look at the ball. It will appear to fall straight from top to bottom.
Then look at the blue circle in the top right part of the page. The spinning disc will seem to change
its fall direction and "fall" leaning towards the left side.
To be honest, I think that it's about tricking your brain into thinking that the ball is constantly moving, while it's not. What is your opinion about the way this illusion works?
