ALARMd is the web alarm that can play last.fm music or your own MP3s that are stored online. You can also have it play YouTube videos and customize when you want the alarm to go off. The downside is that your video can be deleted, the site may be down, and you have to have your computer on. A good time to use it would be when you just need a reminder. For instance you could find a video that will remind you about what you have to do; and then set an alarm to go off fullscreen.
