For people who do not like classical spreadsheets, but need an office tool for tables: With Dagri you can build up tables and save data within. While a spreadsheet uses one single table layout, Dagri can use many tables with different layouts on one sheet. And it gives you more focus on your data. The intention is not another spreadsheet, but something new instead: a data grid application.
TaskRegistry is a calendar, open tasks and time registation program. The calendar is inspired by a classic monthly "one page, one column" calendar sheet.

Tcl (Tool Command Language) is an interpreted scripting language optimized for portability and embedding. It's usually used in unison with its companion Tk GUI toolkit. All language operations are commands in prefix notation, and strings are used as most basic data construct, which both allow for variadic and dynamic uses. TclOO adds object-oriented semantics.
SaVi is software for simulation and visualization of satellite orbits, especially satellite constellations such as Iridium, Globalstar and O3b. It shows and animates movement and coverage over the Earth in two and three dimensions. SaVi can optionally use Geomview for 3D rendering.
tkffmpeg is a simple GUI for controlling ffmpeg/avconv media file conversions. It's implemented as simple Tcl/Tk script. Generic audio and video encoding parameters can be set, such as DVD conversion options, and a progressbar is displayed.
[incr Tcl] is the most popular object-orientation language extensions for Tcl. Its object model is comparable to C++, includes multiple inheritance, classes and instances, and property and method visibility modifiers. It simplifies Tcl/Tk application building, both desktop apps or games; and generally structuring code flow, or chaining classes to C and C++ code. It also comes with new [incr Widgets] and [incr Tk] for building complex and custom widgets.
Savors can visualize multiple data streams from arbitrary input pipes. It synchronizes them in accordance to elapsed time, and arrange sources and their visualizations in any layout.
