Not directly OSR related, but random tables can be very useful. There are a number of programs that do them, here's one more, The Randomizer. Freeware, still a bit buggy, and Windows Vista or later only, but could be useful, since you can add your own entries.
(I find the old NameMage and InnMage very useful. I think they stopped support for Windows, but still can be found on old shareware sites)
