stationary is always simpler. Depends there how much bang for the buck the trouble would be. I'm going with rotation, because i know I'll never be happy later if I cheat out.
With a CRT, not that not only is it going to be more difficult to rotate, but you will also need to consider how it's going to degauss after rotation. Others have automated circuits for this as well, if you search around. I think the Willy Wonka cab had this if I remember. He used a CRT.
