Thinking about a meme using "dark matter"...
Maybe we could take the periodic table of chemical elements and put the word "DARK" in front of every element, starting with Hydrogen:
https://en.wikipedia.org/wiki/Periodic_table
so
Dark Hydrogen (would be the first name to use)
then
Dark Helium
then
Dark Lithium
then
Dark Beryllium
etc...
the good thing about this is we will not run out of consistent names for a while, to name all the following versions.
Also we could create a sub logo for every version that consists of an atomic model with changing numbers of protons/neutrons and electrons.
EDIT: Here is what it might look like:
When we reach Version Dark Gold in 10 years, how awesome will that be?
nice too!
