There are many theories as to what makes the perfect face. Some theories hold that it has something to do with symmetry, with faces like Tom Cruise’s rating high on that scale. Others state that the “average” face, without many distinct features, is the most appealing. For Pedro Berg Johnsen of Norway, doing mashups of famous celebrity faces into one is a favorite pastime.

“I use a bit of Photoshop for final touches and editing, but the actual blending is done in a program called SqirlzMorph,” Johnsen told PetaPixel. “The photo collage or photo merging app is free and pretty easy to use. As for time, everything between two hours and a couple of days. It depends on image size, what level of detail I’m going for, and how invested I am in the project.”
