DesktopLyrics is an application that displays the lyrics of the song currently playing in "iTunes" right on your desktop.

If you don't want to set all your lyrics manually, you can use an application like "Harmonic".
PDF 2 PSP is a simple tool for converting PDF documents and printouts into JPEG images suitable for displaying on the Sony PSP handheld game console. This allows you to download e-books, game manuals, album liners, etcetera to your PSP. Once they're on your PSP, you can read them anywhere. Because of the extensive PDF support built into OS X, any document you can print can be stored as a PDF and converted and downloaded to your PSP. It works best when used with a PSP synchronization tool such as PSPWare, but it can also be used as a stand-alone tool.
