True, it's a bit harder. I started the same place Gygax did -- with the books of Michael Moorcock so it always seemed intuitive for that reason. And it's hard because it's both personal -- Chaotic characters are free spirits and dismissive of law and its spiritual. Chaos is also a physical force that defies laws and boundaries. Humans who touch chaos stuff find their fingers turned to mashed potatoes and their teeth to butterflies.
I always liked this idea -- that demihuman actions on the prime material plane take a physical form on the outer planes. The more people who break laws and defy authority, the stronger the forces in limbo become. If you've not read it try the Elric series for Law and Chaos. You can find paperbacks of the Elric series online for something like 25 cents each and you finish each book in the time it takes you read a magazine.
