QBall is a simple breakout clone, available for Symbian, Windows and Linux: [url="http://homepage.ntlworld.com/mark.harman/comp_qball.html"]http://homepage.ntlworld.com/mark.harman/comp_qball.html[/url]

For Symbian, the application is unsigned, and I've tested it on a Nokia 5800.

Note that it's primarily intended to be played on Nokia Symbian phones, rather than desktops. But I thought I'd compile for other platforms just to see how easy it was - and indeed, compiling for Windows and Linux just worked straight off, with no changes required :)
