Weezencake's Unreliable Algorithm
Mentioned in The Last Continent, this ancient spell could be used to search L-space for unwritten books. However, it was very slow, taking years to put together even the ghost of a page. Placed in the hands of Hex, however, the spell can be made to run thousands of times a second, resulting in the compilation of very large fragments of books like How to Dynamically Manage People for Dynamic Results in a Caring Empowering Way in Quite a Short Time Dynamically. Sometimes, Ponder Stibbons wonders if it's all worth the effort, especially as the results landed on Mustrum Ridcully's desk and sparked his enthusiasm for dynamic management and team-building exercises.
