Griddler is a Java applet that solves griddlers (also called nonograms) such as those that feature in the Daily Telegraph and Sunday Telegraph in Great Britain. You can download the program, source code and documentation (16 KB), which is released under the GNU General Public License.
Note that Griddler is no longer under development, so please do not ask me for new features.
