Asymmetrical Symmetry? Really

So there is this thing about ZBrush and me. I call it an idiot savant program because really it can do things that just have to be seen to be believed. That's the savant part. The idiot part is that you frequently have to put these operations together piece meal from a variety of menus, or find the magic button misnamed and hiding somewhere you would never expect. 

I found a great one today, which does something I would never have thought possible. To use it, you must enable symmetry on your model, which is found on the Transform menu and then turn on the Use Posable Symmetry button right under that. Now ZBrush will let you work on the model symmetrically basing its calculations on the topology of the model rather than an axis. What does that mean? That means that even if your model has been moved off center, or posed (!), ZBrush will still let you make changes to 'matched' parts simultaneously as though they were still symmetrical. It's really amaZing.
