Warp – Twist
This plugin lets you twist a 3D object along any axis. It uses the pivot point of the object to determine the center of the twist. The farther a point is from the center, the more it is twisted. You can quickly twist the object along any or all axes.
Twist options and example
Move the sliders to twist the object around that Axis. Normally you will only twist around a single axis, but you can get interesting results by twisting around more than one axis at a time.
