Extended rotating: Torsion tool

[Crashguard303]

Using the rotate tool (tweak), I had the idea of a tool, which rotates the ends of a selection into opposite directions, creating a torsion.

Try this with a shoelace or other strings:
Put it into both hands, each end between the fingertips of one hand, and rotate one end into one direction, and rotate the other end into the opposite direction, and see what happens!

Seconded. Sometimes helixes asks to be "torsioned" ;]
ATM I need to change part of helix into loop and turn parts separatly.

I use rebuild for this most times, but it is tricky, too.
