Here are links to some software I have created in my free time:
Mattevargen is a very simple Go + WebAssembly program to generate math problems for kids (in Swedish). The code is on GitLab.
Yaics is a simple GNU Social client in C++ and Qt. Since November 2014 Stig Atle Steffensen took over as maintainer of the project.
Heebo was a simple but addictive game in the Match-3 genre for the Nokia N9 and newer Nokia Symbian. There is also a Jolla port and a not-quite-finished WebAssembly port.
JSMandel just draws the Mandelbrot set.
ColourSOM is a simple HTML5 canvas + JavaScript application that demonstrates the Self-Organising Map algorithm by using random colours.
