Sure, but its a little embarrasing :)

The first two methods did not produce a cut, the third created the failed cut.

#1 Scored the glass, flipped it over, and starting tapping the backside of the
glass with the ball end of the cutter.  I'm glad no one saw me doing this as it
was nearly hilarious.

#2 Same as #1, but I used a ball peen hammer to do the tapping.  This might have
worked if I was a little more aggressive

#3 Same as #2, but I placed two 2x4's under the glass, parallel to the cut,
seperated by 10 inches.  Gentle tapping with the hammer didn't do anything, so I
became more agressive.  Eventually I got very agressive, and a single blow
created the failed cut.  BTW, while I succeded in breaking the glass into two
pieces, the cut didn't even try and follow the score mark..

Take Care,
