Escher spheres

Some Escher’s tessellated images can be adopted to spherical surface. First of all it is concerned to his lithographs which show hyperbolic space such as “Angels and Devils”, “Circle limit IV” etc. Above left is the original lithograph “Angels and Devils” and above right is the wooden spherical interpretation of it.

There’s regular way to transformation hyperbolic geometry to spherical geometry. You can read it in this math´s site .

Other Escher’s tessellations also can be applied to sphere. You can see some examples below.
