Rotate a layer?

How many times do you want to rotate it. about what do you want to rotate it about. So many way to rotate.  I saw a scripting tutorial on the web. Its script example was layer rotation. I played around with it and had some fun.  Perhaps you can have some fun with what I turned the tutorial code example into.
