Quassel IRC is a modern, cross-platform, distributed IRC client, meaning that one or more clients can attach to and detach from a central core, much like the popular combination of screen and a text-based IRC client, but graphical. In addition to this unique feature, it aims to be a comfortable chatting program.
HexGlass is a Tetris-like puzzle game based on a hexagonal grid. Ten different types of blocks continuously fall from above and you must arrange them to make horizontal rows of hexagonal bricks. Completing any row causes those hexagonal blocks to disappear and those above move downwards. The blocks gradually fall faster and the game is over when the screen fills up and blocks can no longer fall from the top.
The cdcat is a graphical (Qt based) multi-platform catalog program that scans the directories/drives you want and memorizes the filesystem (including the tags of MP3s) and stores it in a small file. The database is stored in a gzipped XML format, so you can hack it, or use it if necessary. Cdcat can store the contents of some specified files up to a size limit if you want (for example: *.nfo).
Knotter is a highly configurable interlace designer. Interlace patterns are a kind of design historically used as a decorations in many places and by different cultures (some examples are Celtic knotworks and Islamic interlaces). Knotter aims to allow its user to design such patterns in an intuitive way and to provide easy ways to integrate the result into external general-purpose graphic software. For this purpose, designs created within Knotter can be saved in a custom human-readable format and exported as Scalable Vector Graphics and in a wide number of raster image formats.
