board drawing: improving responsiveness

[brownman]

the issue: old people with bad eye-sight may have hard time trying to click the desired board point.

improvement 1: improving the board view, so that mouse move will highlight the target position !

improvement 2: adding animation by replacing the board drawing with html5 canvas.

improvement 3: for gaining more popularity: to arrange some contest between artist at http://jsdo.it to draw that board more nicely!

btw: 10x 4 all ryan ! 4 being so gifted and soo sharing.. ! :)
