A sphere (from Greek σφαῖρα, sphaîra) [1] is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. Formally, a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. [2] That given point is the center of the sphere, and r is the sphere's radius.
In the visual arts, shape is a flat, enclosed area of an artwork created through lines, textures, or colours, or an area enclosed by other shapes, such as triangles, circles, and squares. [1] Likewise, a form can refer to a three-dimensional composition or object within a three-dimensional composition. [2]
Sphere Within Sphere (Sfera con sfera) describes a series of spherical bronze sculptures by Italian sculptor Arnaldo Pomodoro. In 1966, Pomodoro was commissioned to create a 3.5-meter sphere for Expo 67 in Montreal.
Form is a three-dimensional object with volume of height, width and depth. [2] These objects include cubes, spheres and cylinders. [2] Form is often used when referring to physical works of art, like sculptures, as form is connected most closely with those three-dimensional works. [5]

In geometry, a spherical polyhedron or spherical tiling is a tiling of the sphere in which the surface is divided or partitioned by great arcs into bounded regions called spherical polygons. A polyhedron whose vertices are equidistant from its center can be conveniently studied by projecting its edges onto the sphere to obtain a corresponding ...
The artist M. C. Escher is famous for making tessellations with irregular interlocking tiles, shaped like animals and other natural objects. [16] If suitable contrasting colours are chosen for the tiles of differing shape, striking patterns are formed, and these can be used to decorate physical surfaces such as church floors. [17]
Hand with Reflecting Sphere, also known as Self-Portrait in Spherical Mirror, is a lithograph by Dutch artist M. C. Escher, first printed in January 1935. The piece depicts a hand holding a reflective sphere. In the reflection, most of the room around Escher can be seen, and the hand holding the sphere is revealed to be Escher's. [citation needed]
