RScheme is an object-oriented, extended Scheme implementation with a compiler that targets C or (RScheme's own) bytecodes. It has features expected from a modern language: an object system, reflection, modules, namespaces, safe macros, threads, a system call interface (including sockets), separate compilation, and persistence, as well as the formal basis and power of the Scheme programming language. RScheme also features a powerful, elegant foreign code interface.
tk500 is a multiplatform programming and cloning utility for the portable Yaesu VR-500 receiver. It can read the memory image from the radio, display the information graphically, and save it to a file. It can import information from an RT Systems .RDF file and export memory channel information to a .CSV (comma-separated values) file. Users are free to change most settings and write the memory image back to the receiver. tk500 exploits undocumented features within the radio.
XShelf is an application that enhances Drag and Drop operations in MacOS X by providing a shelf where drag-and-dropped items (such as files, text, or URLs) can be stored for later use. Thus, not only can Drag and Drop operations be "paused", multiple operations can be in flight at once. It is the spiritual heir to the NeXT Shelf.
Moho is a 2D vector-based cartoon animation application. It is not an ink and paint tool that requires you to draw and scan each frame of your animation; it provides a set of tools to create an animated cartoon, from drawing and coloring to keyframe animation and multi-layer compositing. It can be used to create animations for video, film, or streaming over the Web.
