HIPPOS' HEADS by Melina
Like Anea's Angels and Austin's Flying Pigs, Melina's Hippos are translational (slide) tessellation art.
As an Escher-style translation, it would be better if we could recognize the outline of each hippo, complete with four legs and a tail. This one... is just heads. As a first tessellation, though, this one is quite good-- the hippo heads' outlines are easily recognizable, even if we were to color the interiors black and just look at the heads as silhouettes.
