FidoCadJ is a very easy-to-use editor, with a large library of electrical symbols and footprints (through hole and SMD). Drawings can be exported in several graphic formats (PDF, EPS, PGF for LaTeX, SVG, PNG, and JPEG). Although very simple and not relying on any netlist concept, FidoCadJ uses a file format containing only UTF-8 text, very compact and suited for copying and pasting with newsgroups and forum messages. This determined its success, being apt for simple mechanical drawings as well a

As a plugin API, Frei0r's main emphasis is on simplicity, to round up the most common video effects into simple filters, sources, and mixers that can be controlled by parameters. Frei0r plugins can be shared by many host applications, avoiding duplicate efforts by different projects. Frei0r is not meant as a competing standard to more ambitious efforts trying to satisfy the needs of many different applications and more complex effects, as it doesn't provides things like an extensive parameter me
OpenCSG is a library that does image-based CSG rendering using OpenGL. CSG is short for "constructive solid geometry" and represents a modeling technique for composing shapes with 3D-primitives which are combined using volumetric boolean operations. Image-based CSG rendering means rendering CSG shapes without calculating their surface in object-space. Instead, the image of a CSG shape is composed directly in the frame-buffer of the graphics hardware by rather sophisticated stenciling and z-buff

Tupi is a design and authoring tool for digital artists interested in 2D Animation, offering an interface experience focused on 8-100 years old kids.
FIM is a lightweight universal image viewer, mostly for Linux. It is highly customizable and scriptable, and for users who are comfortable with software like the VIM text editor or the Mutt mail user agent. You can control it using the keyboard. FIM can open many file formats (even using converters) and it can display pictures graphically, with the Linux framebuffer or under X/Xorg, or in a terminal as ASCII Art renderings.
MinDia is an application for creating, modifying, and presenting multimedia slide shows. A Slide show can contain multimedia elements like images, sounds, and text.
