101, Mendelevium

The Arkanoid/Breakout-like layout commemorates the previous 100 entries in the Pony Periodic Table. Mendeleev once said that he conceived of his table in a dream, so Moondancer is dreaming here (as befits her name).

The colour of each cell represents the characters in the corresponding entry; the symbol and atomic weight are printed only if Mendeleev knew about the element and placed it correctly in his 1870 periodic table.
