Anyone know how to build a rotator nod equivalent with other material nods?

Ya if you want to know how it works, look up transformation matricies since he pretty much implemented one as nodes. The same cocncpet works for 3d vectors as well.

Right, this wikipedia article pretty much explains it: http://en.wikipedia.org/wiki/Rotation_matrix#In_two_dimensions

Doing a matrix multiplication in the material will give you the same result but it's rather expensive, http://abload.de/img/customrotator_028mk3k.png
