#UporDown sparks viral debate over which way this cat is going

It’s the latest viral question that has the Internet buzzing: Is this cat going up or down this staircase?

"Our brain uses the most 'sensible' 3-D interpretation; and mostly -- except when we are being subjected to cunning visual illusions -- this works just fine," Chater said. "But sometimes there are two equally plausible 3-D interpretations of the same 2-D image."
