Reportedly, Monalisa Waves appear only to those who have spent too many hours staring at the Mona Lisa smile. They're like a siren call to the lost and the lonely, beckoning them towards the depths of the ocean.
Avoiding eye contact, they seem to move of their own accord, like the subjects in Leonardo's masterpiece come to life.
Witnessed by only the most discerning of art enthusiasts, Monalisa Waves are said to grant the viewer a deeper appreciation for the human form, but at a steep price: your sanity.
