ViewDog is a viewer for nurbs functions, polygonal geometry, and to some degree for iso surfaces of functions over a 3D domain (via marching cube). It also can be used as a graphical frontend for a number of interpolation and approximation algorithms contained in a seperate library (GUL). Import and export via Alias Wavefront 3.0 OBJ files is possible, so it can be used simply as a viewer for OBJ files, too.
Gumshoe is a program that connects to multiple file sharing services, allowing one to search and download from any of them simultaneously with a consistent interface. Currently only Napster and Gnutella are supported. A plugin system makes it easy to add more. A console UI is implemented, graphical and possibly HTML/HTTP interfaces will come later.
