I did it!

Hours and hours later... I finally accomplished what I thought was the impossible. Has anyone ever done one of these puzzles? Hardest puzzle in the world, but definitely fun. I also have the added satisfaction knowing my genius brother couldn't do it (or maybe he just didn't want to try harder), regardless, his solution was to write a computer program to solve it, the only drawback was that he said it would have to run for a year to find the solution.
