Flickr + Picross = FLICROSS.
Flicross turns Flickr photos into nonogram puzzles using images licensed under the Creative Commons Attribution License.
Every day has a new shared puzzle for everyone.
Grid size preferences are saved locally in your browser (5x5 to 20x20).
Generating puzzles can take a while depending on Flickr response times and image processing.
Need a refresher on nonograms? Here are the rules.
