The Fressia Project is an effort to develop a framework for testing automation. It's intended for users (testers) who want a simple tool that can be used just out of the box. It was originally conceived as part of the QA efforts at the US National Optical Astronomy Observatory. It has been delivered to the community because, despite it still being at early stages, it has proven to be a useful general purpose testing tool. It is designed to provide functional testing, system testing, system integration testing, white (black) box testing, automated regression testing, acceptance testing, etc.
FroZenLight interrelates line arts, mathematics, and cryptography. Circular shaped mirrors which are arranged in a grid-like manner reflect a light ray according to the reflection law of geometric optics. While random positions of the light source produce chaotic reflection patterns, it is possible to position the light source so that beautiful symmetric reflection patterns are created.
FrobTADS is a complete rewrite of the Unix console-version of TADS ("Text Adventure Development System"). It uses curses (or ncurses) and provides an interpreter to play games developed with TADS as well as the TADS 2 and 3 development tools. It adds support for a number of relatively recent user interface features including full support for text and background colors, TADS 3 banner windows, and timed input. It's also much more portable and more easily maintainable, as it's built to modern Unix standards.
Frodo is a free, portable C64 emulator. It focuses on the exact reproduction of graphical effects possible on the C64, and comes in three "flavors" (Frodo, Frodo PC, and Frodo SC) with increasingly higher quality of emulation, but at the cost of higher processing power requirements. Frodo has been ported to a number of systems, including handheld computers. The Unix version can use either SDL, X11, or SVGAlib to display the graphics.
Frogatto is an old-school 2D platformer game starring a certain quixotic frog. It has gorgeous, high-end pixel art, pumping arcade tunes, and all the gameplay nuance of a classic console title. Run and jump over pits and enemies. Grab enemies with your tongue, swallow them, and then spit them out at other enemies as projectiles! Fight dangerous bosses, and solve vexing puzzles. Collect coins and use them to buy upgrades and new abilities in the store. Talk to characters in game, and work to unravel Big Bad Milgram's plot against the townsfolk! At over 30 levels set in 4 different environments, Frogatto is not a flash in the pan, and has the play-time you'd expect from a real video game.
