The INTERNET Database of Periodic Tables
There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.
The 8 Periodic Tables most recently added to the database:

Where Your Elements Came From Periodic Table
The featured periodic table, from Astronomy Picture of The Day (APOD) is color coded to indicate humanity's best guess as to the nuclear origin of all known elements. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.

Circular Model of the Atom: Opposition in the Elements
The Circular Model of the Atom is a circular periodic table that shows atomic structure in addition to periodicity. Unlike any other periodic table or model, it demonstrates that the atomic structure has an inherent dipole magnet that create positve and negative fields and elemental qualities at the atomic level.
The Circular Model of the Atom was created by Helen A. Pawlowski in the 1980s, and published in her work, Visualization of the Atom.
Her brother, Paul A. Williams extended many of Helen's ideas with his examination of the standard model using Helen's Circular Atom Model. This website contains some of Helen's ideas and Paul's writings.
Protein Complexes, Periodic Table of
The Periodic Table of Protein Complexes, developed by researchers in the UK and published in the in the journal Science (Dec 11, 2015), offers a new way of looking at the enormous variety of structures that proteins can build in nature. More importantly, it suggests which ones might be discovered next and how entirely novel structures could be engineered. Created by an interdisciplinary team led by researchers at the Wellcome Genome Campus and the University of Cambridge, the Table provides a valuable tool for research into evolution and protein engineering.
Tetrahedral Twist: Chemistry Puzzle and Teaching Device
A twisting three dimensional puzzle apparatus for the study of chemistry and its history and based upon the Zmaczynski equilateral triangular model of the periodic table of the chemical elements. Each face of the pyramid has a series of equilateral shaped portions bearing portions of the periodic table of elements. The different segments can be rotated around in order to scramble the puzzle. Such portions can be constructed using same or similar technology that was used to design the Meffert PYRAMINX PUZZLE that is similar to the RUBIK'S CUBE design.

Dutch Periodic Table
A Dutch periodic table formulation, Periodiek Systeem van de Elementen, probably from the mid-nineteen sixties: Element 103 Lr (shown as Lw), discovered 1961, is listed but Rf 104, discovered in 1964 is not shown.
Note how this formulation shows the noble gases, He-Rn, both on the left-side and the right-side.
This historic and original periodic table is listed for sale (Nov. 2015) on the Not On The Hight Street website.
