Tiseyko had been deep in thought about other things at the time, and may very well have failed to give the poster a second look — but the kitty printed on it refused to be ignored.
"Suddenly, I noticed a weird movement out of the corner of my eye," Tiseyko told The Dodo. "I stopped, looked closer and thought, 'I probably imagined that.' But then I moved forward and the thing followed me, blowing my brain!"
Turns out, the poster had been pasted up in such a way on the corrugated metal siding as to create an accidental optical illusion. It appeared as though that cat was turning his head as Tiseyko shifted his perspective.
He decided to take a video capturing that mind-boggling trick of the eye.
