Periodic Table for Black Hole Orbits
"We define a taxonomy of orbits that hinges on a correspondence between periodic orbits and rational numbers. The taxonomy defines the entire dynamics, including aperiodic motion, since every orbit is in or near the periodic set." Janna Levin, Gabe Perez-Giz (and New Scientist):

Tomás A. Carroll's Spherical & Russian Doll Formulations
Tomás A. Carroll has devised a spherical formulation of the Periodic Table, and from this a nested Russian Doll formulation.
Tomás writes: "I accept your veiled challenge that it is not possible to formulate a spherical periodic table and propose two solutions for your consideration. The EXCEL spreadsheet shows exactly how I transformed the quantum numbers from the standard 4D Cartesian coordinates to spherical coordinates in 3D, using two different centers. I included cylindrical coordinates too, just for fun."
Pyramid (Stack) Periodic Table
The Janet Periodic Table of Elements (1928) may be re-arranged as a series of square matrices.
The matrices are of different sizes and each matrix organizes the atomic orbitals into square concentric rings. Each cell may be assigned an atomic number which also identifies a “most significant electron”. The matrices may be stacked vertically to form a periodic Pyramid Stack of Elements as shown below.
The sub-atomic particles may also be arranged as square matrices. These matrices may be stacked. Read more here.

Angular Form of the Periodic Table by Kamal Akhtar
"The complete periodic table is consists of two circles, principal circle and auxiliary circle. The principal circle is consist of seven tracks (periods) and eighteen sectors (groups). The auxiliary circle is consist of only two tracks, inner track and outer track. There is no division of sectors in auxiliary circle." Read more in a word.doc. View the full size PT.

Bernard Schaeffer's Quantum Mechanics Consistent Periodic Table
My graphic representation of the orbitals needed for the periodic table is without brilliant colors, but much simpler. It shows the nodes of vibration of the spherical resonator (a spherical musical instrument) also called spherical harmonics appearing in the spherical solution of the Schrödinger equation. It may be noticed that the atom is also a spherical resonator, not of sound but of the de Broglie waves.
The spherical harmonics (feminine word in french!) have been discovered by Legendre two centuries ago, see my book. Only the plane nodes of vibration are shown. The nodes of the orbitals are a 3D equivalent of the Chladni figures (also discovered two centuries ago) on a vibrating plate: "Aufbau" with spherical harmonics.
The random electronic exceptions in the subshells don't appear. The spherical nodes of the orbitals are represented only for the s subshells. This is a much simpler representation than the usual 3D representations. It can be used to represent the entire periodic table as I have shown earlier. The elements are in regularly increasing atomic numbers.

Periodic Table X
Periodic Table X is a periodic table for the Macintosh.
Polymer Periodic Table
"The Periodic Table of the elements by Mendeleev was a historic achievement in chemistry and enabled chemists to see the relationship between structure and properties of the basic elements. Polymers also have a strong relationship between structure and properties and this Periodic Table of Polymers is a first attempt to provide a simple codification of the basic polymer types and structures. The diversity of polymer types makes it impossible to include all of the variations in one simple table and this table only includes the most common polymers. At this stage the Table only includes the most common thermoplastics but it will be extended in the future to include thermosets and potentially rubbers and alloys/blends."

Callan's Periodic Table of Investment Returns
"The first Callan Periodic Table of Investment Returns was published (and copyrighted) by Callan Associates, Inc. in 1999. The Table is updated each year and can be found (free of charge) on Callan's website. As the proud father of Callan's Periodic Table of Investment Returns, and the coiner of the name, I am happy to see it adopted by many in the investment industry, all we ask is for acknowledgment."

Braille Guidebook Interactive Periodic Table Study Set
Azer's Interactive Periodic Table Study Set is designed to make learning about the Periodic Table of the Elements accessible to students with visual impairments or blindness.
The tangible materials included with this study set complement APH's Periodic Table of the Elements Reference Chart and allow students to enhance their understanding of concepts consistent with the National Science Standards.
Inspired by Samir Azer, a science teacher at the Kentucky School for the Blind, this set can assist in the instruction and demonstration of concepts related to the arrangement of the periodic table, atomic structure, ionic and covalent bonding, and balancing of chemical equations to students who benefit from a hands-on, interactive model.
Special attention was given to make the materials tactually discriminable and visually appealing to the target population, yet appropriate for all students regardless of visual acuity:

f--l--A--r--k's Fractal Periodic Table
A fractal periodic table by f--l--A--r--k:
After nearly a year of work and research, the Periodic Table is complete.
I have endeavored to the best of my ability to accurately represent each element as a fractal. The table itself is up to date with current findings and research as of 2008.
Each element has been individually rendered at a resolution of 3200 x 2400, and is available for a full-view in my gallery. Every fractal was designed, composed, and rendered using Apophysis and then the final assembly done with Photoshop.
Many thanks go to Tony (~atd85) for his assistance in rendering quite a few of these elements, and to my wife for her inspiration and encouragement:
