Nawa's V.E.T. Periodic Table & Hourglass
Nagayasu Nawa, the prolific designer of periodic tables, here and here, has come up with an orbital filling periodic table and a corresponding hourglass animation. Nawa writes:
"I have turned the v.e.c. PT into the GIF animation that I call the electron hourglass, 1 second for each element. It takes 120 seconds from 1H to 120 Ubn. I have coloured orbital with colour derived from each shell's name, such as:
- K kiwi
- L lapis lazuli
- M mauve
- N navy
- O orange
- P purple
- Q quick silver"

Ziaei's Circular Periodic Table
Minoo Ziaei writes:
"My father, Manouchehr Ziaei, has an interesting design of the periodic table, which I helped him draw using AutoCAD. He is very keen in introducing [this formulation] to potential interested viewers, he was recommended to visit [the Chemogenesis Database of Periodic Tables] website."

Periodic Table Table Video
Theo Gray collects elements and has put together this awesome Periodic Table Table. This week Reactions explores the science and chemistry going on inside this periodic table.
Step into his office at Wolfram Research, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells and thousands of other chemical artifacts. But his real DIY masterpiece is the world's first "periodic table table". Within this masterfully constructed table-top lay samples of nearly every element known to man, minus the super-radioactive ones.
Theo Gray is 2011 winner of the ACS Grady Stack Award for Interpreting Chemistry for the Public. The Periodic Table Table is a testament to Theo's love for chemistry -- as well as his Ebay buying habits -- and is full of fascinating stories.

Periodical System (Binodic Form): a new mathematical paradigm
By Julio Antonio Gutiérrez Samanez, who writes:
"System devised and prepared by the Peruvian chemical engineer, Julio Antonio Gutiérrez Samanez, deals with a new conception of Mendeleev's Law as a mathematical function and a new description of the process of forming the series of chemical elements according to mathematical laws and dialectical processes of changes quantitative and qualitative under a dynamic spiral architecture in 3D, which is postulated as a new scientific paradigm."

Seaborg's Futuristic Periodic Table
A Futuristic Periodic Table Showing Predicted Locations of a Large Number of Transuranium Elements (Atomic numbers in parentheses) by Glenn Seaborg in 1976. Internal reference number: XBL 751-2036

Seaborg's Evolution of the Modern Periodic Table
By Glenn T. Seaborg, from J. Chem. SOC., Dalton Trans., 1996, Pages 3899-3907:
"In this review, the evolution of the Modern Periodic Table is traced beginning with the original version of Dimitri Mendeleev in 1869.Emphasis is placed on the upper end with a description of the revision to accommodate the actinide series of elements at the time of World War II and the more recent research on the observed and predicted chemical properties of the transactinide elements (beyond atomic number 103).A Modern Periodic Table includes undiscovered elements up to atomic number 118 and a Futuristic Periodic Table with additional undiscovered elements up to atomic number 168 is included."

XBL 769-10601, Periodic Table Before World War II
An internal document of the Lawrence Berkeley Laboratory XBL 769-10601 shows a late 1930s (pre World War II) periodic table.
Note that this formulation erroneously predicts positions for transuranium elements:
- thorium is shown in the group below hafnium
- protactinium below tantalum
- uranium below tungsten
