That's how some are describing a "crazy circle illusion" posted online Monday which has quickly amassed more than 1 million views on YouTube.
The video asks viewers to first watch as the balls appear to rotate in a circle and then "focus on one ball at a time and notice that it follows a straight line."
"This is just another example of looking deeper into something so simple and discovering a hidden pattern," the producers of the video said.
Individuals commenting on the YouTube page left rave reviews, with some calling the illusion "fascinating" and "amazing."
