Prayer Services on Twitter
First, without having to go back, you can read the text of the service in one file. You can also follow @140prayer to see any new ones.
The program, TwitterScripter, is on my files page. The source code is in the file (written in C). It's under a Creative Commons license - though it should be noted that the license specifically prohibits using it for spam. You'll also need to get WGET and another public domain program that's on my site.
It's not the prettiest interface, but it means that anybody with a text file and a bare minimum of ability can run their own timed service without triggering carpal tunnel syndrome.
