You can grab the latest flipper code(current copy uploaded on 11th April 2006) from SVN using the following command
svn co https://svn.sourceforge.net/klickr/trunk/flipper flipper
The Sourceforge SVN repository is not my primary repository since I use a local one, therefore it will be updated only about once or twice a week when I will completely replace the current tree with the latest svndump of the local one.
