skiTunes is a fast, extensible alternative to iTunes. It can use Apple Quicktime, VLC, MPlayer, LAME, and cdrecord. It differs from Apple's offering in that it is written in Cocoa and uses native widgets, as well as supporting formats iTunes doesn't, such as OGG and WMA. Using native widgets will allow it to automatically match the rest of the OS when a theme is applied, unlike iTunes, which requires hacking in order to make it match. It will also offer a skinnable "mini- mode".
iShowU is software to capture and record video from your screen into a Quicktime movie in real-time. Create tutorials, make a demo for the Web, record your favorite game, collaborate on UI design, or show tech support what's really going on with that broken program. It allows you to capture and record anything you can see on your screen, along with audio from any compatible source.
Mr. Random is a utility useful for filling a portable MP3 audio player with music randomly selected from a larger collection situated on a computer hard drive. This is a good idea if you can't make up your mind what you want to hear, you prefer to be surprised by a selection of music you may not have heard in a while, or want to hear familiar music juxtaposed in novel combinations. Mr. Random can be run on any computer with JRE 5.0. It also allows the look and feel to be changed by selecting different themes.
