Here's a few (perhaps arguably) Chaotic archetpes:
"Live Free Or Die!": Loosely inspired by a sort of American revolutionary mindset, the idea is that you don't want the government, or the gods, or anybody else, constraining your ability to do what you want, when you want. You want to pursue your own happiness, and you want others to be able to pursue their happiness as well. This means throwing off the chains that tie you to others and submitting to no one's will but your own. It carries with it a bit of irresponsibility: freedom also means not having to take care of anyone else.
The Barbarians: If you think of towns and cities as Lawful, organized places, the Barbarians represent the chaos and unpredictability of the wilds. It is natural to look out for yourself, to take what you want, when you want, to live off of what the lands provide, to be nomadic, to travel with the seasons, to hunt and gather. "Civilized" life and all of its trappings are unhealthy, corrupting influences, making people fat and lazy and, worst of all, enslaved. City life is only good for the jewel-encrusted kings at the top. You are your own king. You might not have jewels, but you do have the skulls of your enemies. Yes, you might be subject to the whims of bad weather or a wrong step on your journey, but better to face that risk, then to live a life of slavery to some other master.
The Thought Criminal: Chaos, to you, is freedom of thought. You subscribe to no dogma, you criticize every organization, and you seek to exploit the flaws in any system you come accross, ideally to bring it low to the ground, to free others to think for themselves, rather than have thinking done for them. You carve graffitti because to you, it is art. You vocally express your thoughts because to you, this is creative. You refuse to let anyone boss you around -- even if their advice is good, you might go against it out of simple principle. You will never sacrifice freedom for security: so what if it brings danger? Danger is the price of being alive, it's how things change and evolve. Without danger, we're all just boring sameness forever until entropy claims us.
The Zen Master of Random: "Whatever happens, happens." Your philosophy is to take everything in stride, to deal with what's in front of you, and to not worry aobut how it all connects in the end. Patterns are all illusions -- you were born through random chance, you only live through random chance, and, by random chance, someday, you will die. Meaning? A Life Goal? These things are for fools and children. You know better than that. You see what's in front of you. You will not miss the forest for the trees because to you, all a forest is, is a bunch of trees thrown together. Randomly.
The Ditz: Chaos kind of affects your thoughts. They are disorganized and haphazard. You are easily distracted by things that fascinate you, and you have an unsympathetically short attention span. You are like ADD turned up to 11: you cannot focus on anything for very long, and when challenged, you're more likely to try something else than to try a better plan. Your goals are flexible, if they're considered at all: what seems like a good idea now might be supplanted in 30 seconds by a better idea. You can get lost in thought for a while, and this makes it hard to be grounded, but who has time to contemplate infinity when there's so much to
do.
The Individualist-Relativist: The "Well, that makes a nice house rule..." guy.
Every person's experience is limited and localized, and no one has a grasp on the way things work beyond their own ideas. Any theories you have are wrong, because you don't have an experience of
everything, so you can't possibly know how
everything works. You might have a local idea, but as time goes, and chance intervenes, everything changes. Your formulas are scrapped. Your plans are ruined. Your life is up-ended by things you can't possibly predict. It's important to be flexible, and to remember that everyone knows their own life best, but no one knows anyone else's life. No one can tell you how the world works, and, similarly, you can't tell anyone else how the world works. From where you're standing, all you can do is describe your view.
The Hedonist: Enjoy life as much as you can, while you can. Everything goes by fast, so you need to sqeeze as much pleasure as possible out of every moment. Who cares if bringing the world's most expensive wine into the dungeon instead of selling it for a new shield is a horrible idea? Shields don't taste this fine! You'd much rather spend your gold on ale and whores (or whatever) than on investing in a shop or something similarly mundane. You want the world to bring you pleasure, and if you need to slay dragons to get it (dragons: generally not pleasurable!) so be it. All the better to get back to your leisure life. Without the good things in life, life itself is worthless.
7 archetypes is not bad. As far as general advice, I'd say view this chaos cosmologically, not individually: you see the world as a place of inherent disorder and without reason. Any attempt to see a pattern is idiotic, because there is no pattern. Stuff happens, then more stuff happens, you can't predict it, you can't control it. "Chaotic" alignments are about dealing with that as a fact of existence, while "Lawful"" alignments take the opposite view (that there is an order to existence).
Chaotic Good folks generally want the world to be sunshine and happiness and think that order only brings suffering and pain. Chaotic Evil folks are selfishness to the extreme: I do what I want, and screw you. Chaotic Neutral folks are more like the archetypes above, or something like punk rock or Thelema: Do as thou wilt is the whole of the Law.
I'm planning on referring back to this thread occasionally for food for thought.
