Hi Tim,

> Ummm this makes no sense? Why the random angle?? Definitely not mirroring with any logical sense? lol

Well it's going to call the getFrame() function on what is given to the MirrorFrame input. That's located in geometry.js but I'm not quite sure what it's trying to do with other kinds of input like single vector like you're giving it. Maybe that's taken as the z axis direction of the plane.
