This is the moodle Quiz UI version 0.52. Much functionality is still missing and is represented by placeholder UI elements.

The other diff is reverse (new ui -> fresh moodle 1.9)since that is how eclipse decided to do it. In the next version I will try to provide a single diff file, this was kind of a temporary solution. So you will probably need -R wtih patch to use it. See 'man patch' for more info. Also it contains quite a few extra whitespace changes in lib/weblib.php which I did not put there. 

patch -p5 -R <moodle.diff
patch -p5 <weblib.diff

then, copy the rest of the files in the moodle directory. /mod/quiz/edit.php , /question/type/random/icon.gif and /question/type/essay/icon.gif should be overwritten.

The current demo is available during development in Summer 2008 at:
