birectified 5-simplex, a convex Uniform 5-polytope.
Tesseract, one of the 6 Convex regular polychorons (4- Polytope)
graph of Tesseract, one of the 6 convex regular 4-polytopes ( Polychoron).
graph of the 120-cell hecatonicosachoron, one of the 6 convex regular 4-polytopes ( Polychorons).

Root system is a configuration of vectors in a Euclidean space satisfying certain geometrical properties. The concept is fundamental in the theory of Lie groups and Lie algebras. (See Differentiable manifold, Adjoint endomorphism, Abstract algebra, and Galois theory).

Lie algebra
Spirograph for drawing Hypotrochoids and Epitrochoids.
Harmonograph employs pendulums to create a geometric images such as Lissajous curves which describe Complex harmonic motion. (See Fourier series).

Lorenz system (Lorenz attractor)
Mandelbrot set
Mandelbrot set detail
"Seahorse tail", central endpoint is a Misiurewicz point.
