I don't know if anyone is interested, but my simple Rouser alarm clock application is available for download from here: http://kristopherjohnson.net/download/Rouser-1.0.dmg. Source code is included, and it's all free under an MIT-style license.
It mostly works. The Print and Help commands don't work. OS X 10.3 (Panther) is required; I don't know what it will do (if anything) under older OS X versions.
For the next version, I plan to provide the following:
- a better application icon
- a help file
- preferences/options settings
- AppleScript support
If you try it out, please let me know what you think.
