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: 2014 Press Release Story Elements

From Kotaku:
While visiting the Nagoya City Science Museum, Twitter user Kantaku noticed something very cool, the coin lockers.
The name of each element is written below each symbol in Japanese, allowing visitors to store their belongings in Helium, Calcium, Oxygen, Potassium and more.
The number of each locker corresponds to the element. So, locker 21 is Scandium as it's the twentyfirst element on the periodic table. Locker 3? It's Lithium, like it is on the periodic table, and so on. Dibs on Krypton!

Top of Page 2014 Janet Rajeuni
By Philip Stewart:
Janet Rejuvenated, with acknowledgement to Valery Tsimmerman for the idea of using one square per orbital and of shifting the blocks so that each row represents one value of n, the principal quantum number.
The main objection people make to Janet is that He is placed at the head of the alkaline earth metals although it behaves as a noble gas. The essential answer is that electronic structure explains behaviour and not vice versa; like Ne (and unlike Ar, Kr, Xe and Rn), He has a complete shell. Similarly H, like C, is half way between a full and an empty shell, unlike the alkali metals and the halogens. I suggest a new argument: nobody finds it strange that the p block has a row of nonmetals at its head (and that half its members are nonmetals), so why not the s block?

"I would like to submit you an hexagonal periodic table. It's structured in different rings. The elements are ordered on their metallic characters so in the inner rings there are noble gases and nonmetals while in the outer rings there are alkali and alkaline earth metals. I based the order on the typical metallic characteristics: low ionization energy, electron affinity, etc... "

MONOGRAPH ON ATOMS, BY Dr. N. Naveen Chandra, 543 Bellamy Road North Scarborough, On, M1H1G5, 416 439 6630, chandraalex@hotmail.com © N.Naveen Chandra, 2014.
Abstract
A new way of graphical representation of atoms is developed and presented here. Atoms are recognized as functions of two variables A(r,Θ), where r =2,10,18,36,54,86,118 (given arbitrarily r=1,2,3,4,5,6,7) represents period and Θ representing group, is actually the angle between the groups. A mathematical solution is obtained for Θ having three distinct values of (π /9) radians, (π/18) radians and (π/27) radians which define three super groups satisfying the equation 15(π/27) +10(π/18) +8 (π /9) =2π. 15 groups of two Atoms with a transition zone of (π/27) radians is nominally called Grey Super Group (GSG). 10 groups of which 9 have four Atoms and 1 has two Atoms, also including a transition zone of (π/18) radians, is nominally called Blue Super Group (BSG). 8 groups of which 7 have 6 Atoms and one has 7 Atoms, including a transition zone of (π/9) radians is called Yellow Super Group (YSG). The group with 7 atoms is the so called reference group of Atoms 2, 10, 18,36,54,86 and 118. The GSG has 30 Atoms, the BSG has 38 Atoms and the YSG has 49 Atoms. The Atom 1 is at the centre of the Hub and does not belong to any group or period and has coordinates of (0, 0). Atom 1 having no neutrons is unique.
