Free alarm clock software for mac

This is my first real OSX Cocoa Application. I dont have an alarm clock, but I do have an LCD iMac next to my bed. I searched around and didnt find a simple digital clock screensaver, so I wrote this. Its also been a great exercise in learning Cocoa and Objective-C.
Features:
- Adjustable clock font style, size, and color
- Customizable clock format
- Clock can remain motionless, or move around the screen using different effects

MP3 Alarm Clock is an alarm clock program that supports many audio formats such as MIDI, WAV, and MPG, not just MP3s.
Unlike other alarm clock programs that only have a preset number of alarms, MP3 Alarm Clock supports an infinite number of Alarms, each with customizable playlists, date, time, volume, snooze times, and many other settings so you have complete control over your alarms.
Enhancements:
- Alarm creation window now has buttons to add and remove all songs to/from the playlist
- The playlist now advances to the next song every time you snooze.
- A randomize playlist feature has been added
- Gradually Increasing Volume is back from the Mac OS 9 version
- Decreasing Snooze Time - each time you snooze, the snooze time cuts in half
- Today button is back!
- Whats Improved
- Application now saves preferences to file every time you add, edit, or delete an alarm
- Snooze sheet now stays while you are snoozing - more intuitive
- Reworded some of the text to improve continuity
- Unnamed alarms now display as "Untitled Alarm"
- And other minor changes have been made
- An alternate user-supplied icon has been provided
- Bug Fixes
- MP3 Alarm Clock now always jumps to the front when an alarm triggers
- Customize Toolbar now works if no windows are open
- Should save prefs for users who log in as root (btw: stop logging in as root!)
- And other minor bugs have been squished.

24 hr. Digital Clock is as the name says a LCD-type display digital clock. Time is displayed in 24 hour format.

Completly freeware for non-commercial use.

AlarmThingy is a quick Cocoa program I wrote recently, partly to learn Cocoa, but mostly because I wanted an alarm clock program tailored specifically to me.

Itll let you set an alarm to go off at a specific time or in a certain number of minutes, and then itll play a random track from an iTunes playlist.
To add variety, it wont play any of the last 10 tracks it has already picked. That little gimmicky feature is really the only thing this program does that other programs dont.
I had a similar alarm system set up in Windows, and basically I wanted the same thing in Mac OS X.
