<a href="http://woodgears.ca/eyeball/index.html">The eyeballing game</a> is an interesting game that challenges you to "eyeball" distances and angles for fabulous prizes, fortune and fame. You have as much time as you like to perform each of the following tasks three times: <ul> Make a parallelogram by dragging one corner to the correct position. Identify the midpoint of a line Bisect an angle Find the center of a triangle Find the center of a circle Make a right angle out of two line segments Find the point of convergence for three line segments </ul> The top ten scores of the last 500 games are displayed for all users and your own top four scores show up below those. My top score so far is 2.13, as shown below: <img src="{att_link}the_eyeballing_game_round_3.png" href="{att_link}the_eyeballing_game_round_3.png" align="center" class="frame" caption="Second Place - 2.13" scale="50%"> The chart at the end shows your score relative to the last 10,000 games and 2.13 was right up there! I think I can beat it, though; at one point, I had 1.54 after two rounds, but fell apart completely and washed out with a 2.23. I must have suspected that something like that would happen because I took a screenshot after the second round, as shown below: <img src="{att_link}eyeballing_game_-_1.54.png" href="{att_link}eyeballing_game_-_1.54.png" align="center" class="frame" caption="After Two Rounds - 1.54" scale="50%"> As for tips? Try squinting to blur things up a bit; sometimes that helps you to estimate distances better. The consistently most difficult ones for me? Finding a midpoint, followed by the parallelogram and finding the center of a triangle (in the latter two cases, the less-flattened shapes seem easier).
