According to the final formula%2C the line should pass through M%2BN-1 %3D 66 squares %28since the gcd %3D 1%29.  However%2C I only counted 60 squares colored in grey by the applet.  Furthermore%2C the line appeared to pass through grid nodes%2C which would indicate a common divisor %3E 1%0D%0A%0D%0AIs there a problem with the applet%27s drawing resolution capacity%3F  I see that %2240%22 is the limit for M and N.  Could there be a problem with the applet%27s algorithm when MAX values are employed%3F%0D%0A%0D%0AOtherewise%2C this is an extraordinary web-page.  Very fun%21%0D%0A
