Is there a way to animate in polar coordinates?

I want to have objects rotate about a common axis with the angular velocity increasing over time and the radius decreasing. It would be easy in polar coordinates.

Is there a way to do this? I tried using a vortex, but not too good for that.

thanks

This question needs to be moved to the other animation thread since this question was placed in the wrong section.

You could always try using “Alt ,” to manipulate center points (object and pose mode only), then try rotating (moves the object around the 3d cursor without affecting the object’s rotation) and scaling (increases/decreases the distance between the 3d cursor without affecting scale). Hopefully that should work.
