Do you see a broken watch or a green hourglass?

Mark Millar—who you may know as the writer of Kick-Ass, Kingsman: The Secret Service, and Starlight—has a new comic coming out Wednesday.

But it’s the cover art created by artist Sean Murphy that’s already stirring up chatter on social media. 

The new Image Comics series Chrononauts follows two science geniuses on a time-traveling adventure, perhaps making it fitting that the cover of the first issue features an optical illusion that will be easy for most readers to miss.

The optical illusion can be found in the watch featured on the left side of the cover. While the majority of people will just see a broken watch, apparently some may see a green hourglass on a purple background.

The creators explained the illusion on Twitter. According to Millar, Murphy made the illusion with the help of a neurologist and there’s no way to see anything in between the two.

The illusion may not have gone quite as viral as that infamous dress, but it has still managed to cause some debate online. A few have said they can see the hourglass, including actor Nick Frost, while the majority just see the watch face. Others don’t think there’s an hourglass there to see at all. 

No matter what you see in the watch face or think of the illusion, there’s no doubt it has succeeded in drawing attention to Millar and Murphy’s new series hitting shelves March 18.
