  Quarks can be represented on the faces of the 3x3 Rubik's cube with the help
of a symbolic representation of quarks and anti-quarks, that was delevoped
originally for a deck of elementary particle cards, called Quark Matter Card
Game. Cubing the cards leads to a model of the nearly perfect fluid of Quark
Matter on Rubik's cube, or Qbe, which can be utilized to provide hands-on
experience with the high entropy density, overall color neutrality and net
baryon free, nearly perfect fluid nature of Quark Matter.
