I don't know how to do it myself, but was thinking if someone could code in a "picture" of vortexs like when you look at the fire you see the fire. Anyway, another idea to ponder while bored.
Whereas a fire is something all/most have seen and everyone can agree of how it is supposed to look, a vortex is a magical thing and it would be quite difficult to agree on what its supposed to look like. Also painting a picture kindof beats the purpose of fantasy.
However, if someone can come up with a cool-enough looks, im all for it.
Artic, it's a vortex not brain science.. A vortex is a vortex? I believe it's also described somewhere..
I think it's a good idea to add a fancy ansi sequence for them, it might at least keep those sorcerors from napping so they could marvel at their nifty spell.
