Right, you mention a computer, so that what are you patenting is the computer, not the pure algorith itself. And of course, the difference is pretty much nonexistenct for practical purposes, but since we were working with a contrived example of just publishing source code, I think that was one of the few times that difference mattered.

If i recall Chimera aren't pleasent things and there always used to suggest pestilence etc in literature. Now that I think of it Minotaur isn't so hot either. He spent all his time trapped in a maze. Do you really want that connotation with a software product?
