Software

Here are links to some games and other toys that I have released as free software.

Heebo

A simple but addictive game in the Match-3 genre for the Nokia N9 (MeeGo Harmattan). The game has got over 46,400 downloads on the Nokia Ovi Store (as of May 3, 2012).

Yaics

A very simple identi.ca/StatusNet client in Qt. It also includes a client for Nokia N9/N950, which is usable, but perhaps not quite ready for general adoption.

Download for Nokia N9/N950: yaics_0.1.1_armel.deb (Updated April 26, 2012)

Daily Comic

A simple web comic viewer. It uses the server maintained by Johan Paul for his WPDailyComic application. My comic viewer is written in Python and PySide.

Blocks

A Qt-based game inspired by Blocks Mania for iOS. At the moment the basic mechanics are there, I just need to make some levels!

ColourSOM

A Java applet that demonstrates the Self-Organising Map algorithm by using random colours as training vectors.
