Somewhere in Lesson #09: "Now we move the star. The star starts off in the middle of the screen. The first thing we do is spin the scene on the x axis. If we spin 90 degrees, the x axis will no longer run left to right, it will run into and out of the screen." If we spin on the X-axis the X-axis will not change. Its orientation will remain the same. However if we spin on the Y-axis, then the X-axis will do as described. So... seeing as this site has been around for years and this has not been noticed... one would almost think that it is correct... But I don't think it is... Or am I missing something?

Yes, he's talking about rotating about the y axis, therefore spinning the x-axis and z-axis.
