Eagle Mode is a zoomable user interface (ZUI) with file manager, file viewers, games, and more. This project is about a futuristic style of human-computer interaction, where the user can visit almost everything simply by zooming in. It features a portable C++ toolkit API for developing such ZUIs, and it features the Eagle Mode application, which provides a virtual cosmos with plugin applications. The most important one is the professional file manager with its rich, scriptable command set. It integrates file viewers for most of the common file types, as well as an audio and video player. Furthermore, the virtual cosmos contains a chess game, a netwalk game, a 3D minesweeper game, a multi-function clock, a stock watchlist, some fractals, and a Linux kernel configurator in form of a kernel patch.

Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives top speed performance, even on very big circuits. I have succesfully managed to simulate complete VLSI projects with this tool, both digital (Verilog / VHDL) and analog (Spice). Schematics can be printed in SVG, PNG, PDF, formats. XSCHEM runs on Linux or other Unix-likes with Xorg server and on Windows with the Cygwin layer and required tools installed. Can be found also on github: https://github.com/StefanSchippers/xschem
