TOPIC: sudoku, logic puzzles
I've intended to post something on this for a long time: for the perfect sudoku puzzle experience on a Mac, try out UniSudoku (just $15 and downloadable at http://www.unisudoku.com/). David Ross is apparently a GUI-programming genius and has produced possibly the most perfect sudoku puzzle software/interface ever.
With a little practice you too can enter the beautiful heightened sudoku flash zone where the world seems to disappear and it's just you racing through an alternative sudoku universe. With a finely-tuned mouse the "flow" experience can be breath-taking and addictive.
Quick screen shot below. Let me know what you think!
