FUNNY MIMICS by Jasmine L.
This is a classic translational (slide) tessellation. You can tell it's a translational tessellation because the faces are all at the same angle-- they're simply copied and moved along the X axis (left-right) and Y axis (up-down), without rotating.
Is this a tessellation? Well, if we look at the faces NOT as faces, but as abstract shapes, then yes, this is a tessellation. However, if we say the shape is a face, then we have to ask "Where's the body?" and "My goodness, what happened to the neck? It's either hidden behind the face below it (overlap-- a no-no in tessellation) or these guys have reeeeeally long ears and small pointy chins."
See this example for a clearer explanation of why "Funny Mimics" is...and is not...a tessellation.
So, which is your favorite face? Mine's the pirate...or maybe the brown kid with his orange hair.
