For colons, I have always enjoyed Harold Nicolson, who would often use three or four in a sentence, like he did in Some People (1926), one of my favorite books, ever. Malcolm Lowry also made liberal (and visual) use of colons. Below is my favorite sentence from "The Greyhound", the first "chapter" of his posthumously published novel October Ferry to Gabriola (1970), edited by his wife, Margerie Bonner:

"The bus changed gear, going up a hill: beginning: beginning: beginning again: beginning yet again: here we go, into the blue morning."
