3Doku brings the traditional Sudoku game to the third dimension. In a 9x9x9 cube, 27 Sudoku schemas intersect one another along the three axis. Every 9x9 bi-dimensional schema must be solved, keeping in mind that every single cell belongs to the selected schema and also to the other two placed on the orthogonal planes. With 4 difficulty levels and 4 initial values distributions, you can customize your game and have every time a new exciting challenge to solve.

ActoTracker is an application for keeping track of activities on your desktop so that you don't have to. Think of it as an app for bookmarking desktop documents and applications. It can also bookmark things that are not usually tied to a URL such as Outlook email message or Filemaker records. It can be extended to handle additional applications by writing custom AppleScript plugins. ActoTracker is somewhat inspired by the GNOME Activity Journal (Zeitgeist framework), and it tries to solve a similar kind of problem for the end user, although in a different way.

It is easy to use by both users and programmers and can store almost all imaginable data, including multiple phone numbers, emails, and addresses, photos, AIM/Jabber/ICQ/Yahoo IM details, and notes. It supports drag-and-drop and integrates well with GNUMail.
