The Sunday Puzzle

ixThought that you might enjoy a puzzle to help pass the time today. The image on the left shows the number 9 in Roman numerals.

Your task is to draw one single continuous line and turn this into a 6. Feel free to say if you have solved it and how long it took you, but no giving the answer. I will reveal the solution, and source, on Monday. Enjoy.

Quick Update: Someone has just emailed me another solution, so there are TWO ways of solving the puzzle.

The answer to this puzzle, and 100 others,  can be found in a new kindle ebook called PUZZLED, and is available in the UK here and USA here.

The Dancer Illusion

Quite a few people have sent the following illusion to me. Basically, as you look at the dancer, she will suddenly shift from moving in a clockwise to anti-clockwise direction. A few sites are suggesting that this is some kind of test of left and right brain thinking, which is obviously rubbish, but it is a nice effect. As yet, I have not been able to find out who actually created it, so if anyone knows, please drop me a line.
