Sounds: The Sound Change Applier. This page describes a simple program which can apply a set of sound changes to a lexicon.
You can use sounds to help work out a reconstruction for actual languages, to create plausible descendants of a conlang, or in fact to make any structured set of lexical changes to a database of words. I suggest using the more powerful SCA² instead. It has many more features, works in your browser, and supports Unicode. The Mythopoet's Manual - Contents.

In October, 2004, I posted 30 days of world-building exercises to the NaNoWriMo discussion forums. These are short, 15-minute exercises that can help you make crucial decisions about your world, and what you want your story to say about it. These exercises have been edited for general use and re-posted here. So, give yourself 7 and a half hours this month-- 15 minutes a day-- to build a world.
