The included personal VCR can be programmed not only locally but also via a Web interface from anywhere.
Kate is a codec for karaoke and text encapsulation for Ogg. Most of the time, this would be multiplexed with audio/video to carry subtitles, song lyrics (with or without karaoke data), etc, but it doesn't have to be. Moreover, the motion feature gives Kate a powerful means to describe arbitrary curves, so hand drawing of shapes can be achieved. This was originally meant for karaoke use, but can be used for any purpose. Motions can be attached to various semantics, like position or color, so scrolling or fading text can be defined.
Py-Lepton is a high-performance, pluggable particle engine and API for Python. The engine is designed to be very flexible and does not rely on any other libraries directly. You can use it either with OpenGL (via pyglet or PyOpenGL), or with pygame by selecting the appropriate renderer. Examples are provided using pyglet and pygame. Note that this is in an alpha state, so expect the API to change somewhat in future releases.
Gimp User Filter is a work-alike to Adobe's Filter Factory. It is a generic image processing plug-in that can be used to create new filters for The GIMP without having to go through the process of learning about The GIMP's SDK. Many freely available filters that have been created for Filter Factory can also be used with this plug-in.
Seamstress is a portable library that implements Avidan and Shamir's seam carving technique for content-aware image resizing. Seam carving works by removing the "boring bits" from an image, so it can change the aspect ratio of many images without changing the shape of the objects inside.
