I’ve used wxWidgets back when it was wxWindows but haven’t played with it lately. So I loaded up Code::Blocks (with wxSmith) and wrote a little game. The premise is “concentration” but instead of cards, the game loads up random images from Google based on your choice of keywords. It isn’t perfect. The search sometimes returns strange things (just like any search) and if you get the same picture twice (unlikely but it happens) it can be confusing.
Anyway, for a quick throw together its not bad.
Since wxWidgets is cross platform, the game ought to run under Windows as well as Linux (where I developed it).
