For a long time I've assumed that some dev had an interest in physics or geometry when naming Zaxis, as his name isn't actually Zaxis, but Z-axis. Today I was thinking about it and decided to ask if anybody knows if there was anything more behind it. Is there perhaps a science joke here that I'm not getting? Is it nothing more than a programming reference: http://www.computerhope.com/jargon/z/zaxis.htm
