Brick Out(http://www.newbreedsoftware.com/brickout/) is a game where you move a paddle back and forth to bounce a ball around the screen. Use the ball to break all of the bricks at the top of the screen. It was written with the Agenda VR3 PDA in mind, but works on anything that supports Xlib.
Agendaroids(http://www.newbreedsoftware.com/agendaroids/) is a game where you maneuver a space ship in a field of asteroids, and shoot at them to break them into smaller pieces. It uses vector-based graphics with fixed-point trigonometry, so it runs well even on the FPU-less VR3, but it also runs on any other Xlib-based system.
Aliens(http://www.newbreedsoftware.com/aliens/) is a simple Xlib-based Space Invader game designed for the Agenda VR3 PDA. It is played with the PDA device held sideways, and using the buttons on the face of the unit.
TI85 Emulator for Unix(http://project.terminus.sk/ti85emu/) works on common Linux boxes and is in use on Agenda VR3 Linux PDA too. The X toolkit can be easily replaced by the Xlib or something else; if you don't like FLTK or GTK.
Monica(http://www.pcbypaul.com/linux/monica.html) is a small monitor calibration tool using the FLTK library. It works as frontend to xgamma to alter the gamma correction for XFree86 or Xorg.

GoWeather(http://sourceforge.net/projects/goweather/) displays an attractive representation the current weather conditions for a particular location, along with upcoming weather forecasts. The source of the data are small, text-based reports in a standard format (METAR and Zone Forecast (ZFP)) made available from an unchanging, reliable source (the National Weather Service (NWS)). GoWeather is FLTK-based, has a small form-factor, and the data files are very small and can be accessed offline. This means GoWeather is suitable for Linux handhelds (like the Agenda VR3 PDA).
xmltVR3(http://xmltvr3.sourceforge.net/) is an Electronic (TV) Program Guide for the Agenda VR3 PDA, using data gathered by the various grabbers of the XMLTV-Project. It is planned to be extended to act as a remote control for TVs and VCRs, to make use of the integrated infrared transmitter.

It is geared for business-style application development with database support (ODBC). All the widgets support database connectivity. A special CDialog class makes editing database records very easy. Every widget can be connected to the field, and CDialog can be connected to the database table.
vtkFLTK(http://vtkfltk.sourceforge.net/) is a small C++ class library that simplifies the development of FLTK event-driven interfaces for use with VTK. It allows the composition of complex graphical interfaces to complex visualization facilities by bridging disparities between FLTK and VTK event and windowing system handling. license: BSD License (revised)
