for me to find the Underworld CD I was looking for. Why they have to publish 1,000,000 different versions of the same album, I dunno, but oh, well. Hopefully the ebay-guy I bought it from is good to his word.
Of course, I don't really understand how it works, but it's nice to know that, in principle, one can disassemble a golf ball into a finite number of pieces and reassemble it into the planet Jupiter.
