At what point do a series of angled lines become copywritable? After two lines? Three? Can I copywrite two lines meeting at 67 degrees, and then claim angles 65-69 as like works? Can I then claim that your maze contains my intellectual property in several places? (And would you still feel your rights were violated had kraft taken two of your mazes and glued them together?)

With regard to your question, it depends on whether it passes the Threshold of Originality: http://en.wikipedia.org/wiki/Threshold_of_originality

It's a matter of arriving at the result. In other words, what matters is whether you used the original (and with what intent), not whether you arrived at the same result. Unfortunately, both of these are hard to prove.

Not exactly intuitive, I'd agree; see e.g. this: http://ansuz.sooke.bc.ca/entry/23

(Oh, and it's "copyright")
