Alchemy is a nifty little program for finding word ladders. A word ladder is a sequence of words made by changing one letter ata time, eg. LEAD LOAD GOAD GOLD. Given any two words, Alchemy will find the shortest ladder between them, or beep if none found. It can also find random ladders and longest ladders.
