new entity i made up called "func_funkytown"

[The Happy Friar]

it combines the properties of a func_bobbing & func_rotating in to a single entity.  Basically reduces entity count if you want something to bob & rotate but not be an animated model.  I bound a model to it.

This is giving me a few ideas, mind publishing the code so we can look?

[The Happy Friar]

it's just as simple as I describe.    I literately combined idbobber & idrotater together.
