Rastersplit plasma are cool indeed |

AFAIK, plasma is the effect where colour transistions are plotted on the screen in various interfering more or less repeating patterns. |

grahams definition is kinda best :) the "plasma" demo effect is kindof a visualation of the molecular density in a certain medium (which happens to be in plasma state).
another famous visualisation is the so called "lava lamp" =)
(that definition excludes the so called double-sinus plasma routines - these dont visualise a chaotic plasma state, but a simple cyclic pattern. BORING! =P) |

that definition excludes everything we call a plasma regarding demos. |

not at all. a perlin noise plasma for example is pretty close. even with simple sinus functions you can make something that atleast looks very convincing (you'll certainly need more than two though =P). |

Yeps, in fact even JPEG images are just many small 8x8 pixel sinus plasmas :D |

For the Dutch plasma could also be a pissing mother...

to begin with plasma is a state of matter (ionised gas) where atoms and electrons become (partly) separated. there's no molecular plasma what you blabble about, thus there's no fx that - even by mistake- can look "kindof" the same. |
