The eyeballing game

Thanks (I think!) to Stephen Downes for the pointer to this today. Great fun. Except that I have work to do, darn it!

You have to judge by eye where three lines will converge, where the centre of the circle is, etc. and the system rates your margin of error. As with golf, the lower the score, the better. Of course you just know that I wouldn't have pointed to this if I hadn't kicked butt at it ;o)
