A Klein bottle, an example of a surface that is non-orientable — one with no distinction between the "inside" and "outside".

A Penrose tiling, an example of a tiling that can completely cover an infinite plane, but only in a pattern which is non-repeating (aperiodic).

This is the method of constructing a golden rectangle with a compass and straightedge.

A dodecahedron is any polyhedron with twelve faces, but usually a regular dodecahedron is meant: a Platonic solid composed of twelve regular pentagonal faces, with three meeting at each vertex.

The tesseract, also known as a hypercube, is the 4-dimensional analog of the cube. That is, the tesseract is to the cube as the cube is to the square

These are all the connected Dynkin diagrams, which classify the irreducible root systems, which themselves classify simple complex Lie algebras and simple complex Lie groups. These diagrams are therefore fundamental throughout Lie group theory.

The Lorenz attractor is a non-linear dynamical system derived from the simplified equations of convection rolls in certain atmospheric equations. For a certain set of parameters the system exhibits chaotic behavior and forms what is called a strange attractor.

A logarithmic spiral is a special kind of spiral curve which often appears in nature. This is a cutaway of a Nautilus shell showing the chambers arranged in an approximately logarithmic spiral.

A cuboctahedron is a polyhedron and an Archimedean solid. It is quasi-regular because although its faces are not all identical, its vertices and edges are. It gets its name from the fact that it is both a rectified cube and a rectified octahedron.

Part of the Mandelbrot set, an example of fractal geometry described by dynamical systems.

This picture shows the four conic sections: Circles, Ellipses, Parabolas, and Hyperbolas.

This fractal, a Buddhabrot iteration, is believed by many to have a resemblance to the Buddha. The fractal is special rendering of the Mandelbrot set, discovered by Benoît Mandelbrot.

This fractal, one of the most famous fractals in mathematics, is part of the Mandelbrot set, discovered by Benoît Mandelbrot.
