A high school friend of mine did a 'Pi tour' of the library where they read the 'nth' book on the shelf for each 2 digits of Pi. So book 31 on the first shelf, but 41 on the next, 59th on the next. There wasn't anything magical about using Pi for this, it merely provided the backdrop and gave some 'flavor' to the choices other than random. He had to get creative when the shelf didn't have enough volumes on it (typically he would do banker's division by 2).

The result was he found some interesting books (and some turds too). I could not argue with his logic that 20 years later none of the information I got sitting through an hour of the "Six Million Dollar Man" would be useful but something he got from one of the books might be.
