Solving 6-piece Burr Puzzle

Not really computer related, but rather solved with a computer...

I have one of those 6-piece block puzzles that has been apart for some time. I decided to look online to see if I could find a solution. First I learned that it is called a 6-piece Burr puzzle; then I discovered that there are too many different combinations that I would be luck to find a solution.

Then I ran across an IBM Research site on Burr puzzles. After looking through many of their solutions, and not finding a match, I discovered their applet to solve any Burr. I just entered the cuts of each of my 6 pieces, and within seconds it had the solution for me. And if that wasn't enough, it showed me piece-by-piece how to reassemble it.
Truly I am impressed.
