There's a scene in my novel Homeland (the sequel to Little Brother) in which the first 1,000 digits of Pi are featured; when it came time to produce the audiobook edition, poor Wil Wheaton — the narrator — ended up reading out Pi for four solid minutes, with some entirely understandable difficulties. Nick Land set the reading to music, creating quite a delightful little tune!
