This is a simple scoreboard for taido jissen. It's designed to be run on a Windows computer with a secondary screen attached.
The first window opened is the control panel used to set the player names, scores and warnings and operate the timer. Open the scoreboard by clicking the obvious button, move the scoreboard window to the secondary screen and press Ctrl+F for full-screen (ESC to leave full-screen).
The source code is written in C# WPF using Visual Studio. In order to get started using it, just clone the repo, build and run. The latest binaries are found under Downloads...
