Old school effect: the radial blur

For this episode of the graphics dojo I've implemented the classic radial blur effect. The core radial blur effect is implemented with per-pixel manipulation, which Qt lets us do quite elegantly using the QImage class. The final dojo example uses the radial blur effect in combination with scrolling text drawn using QPainter to create a nice visual impression. Below is a screenshot of the effect as well as a recording:

As usual, the source code is available from the SVN repository: svn checkout svn://labs.trolltech.com/svn/graphics/dojo/radialblur
