A small clarification

I think I may have been a little too flippant in my last posting, 'cos at least two people seemed to think Flickr Sudoku was a spoof page about hamsters. :-)

So a bit of clarification:

Flickr Sudoku is a fully working pictorial puzzle generator. It takes pictures from groups or tags on flickr and turns them into a genuine sudoku puzzle that can be solved. It's also able to check completed puzzles for accuracy and will indicate where any errors have been made.

Some feeds are better for making sudoku puzzles than others, it tends to work best with lots of random pictures. While it's fun to have a sudoku board made of hamsters, it's quite taxing to solve cos hamsters are kinda similar-looking. :)

Here are some sample presets of good feeds for Sudoku boards (well they were good when I tried them earlier, the feeds are changing all the time):

catchy sudoku, from the "catchy colors" pool.

circle sudoku, from the "circle squared" pool.

And one for the sadists:
sudoku sudoku, made with the latest pictures with the tag "sudoku"

I'm working on improvements still, I've added 3 extra puzzle patterns tonight, which are provided by a separate XML feed so eventually there could be dozens of puzzles to solve. Siobhan also pointed me in the direction of the Flickr API, so I might be able to implement things like custom feeds from individual user photo streams. It kinda does it already, but not with any finesse!
