Wrangle Node Example - Pop Spin?

Pop Spin Tips:

The goal in this example was to maintain the original orientation but have the particles begin to spin at a given frame using the pop spin node. This can be achieved using a point wrangle node to set the initial orientation.

Inside the pop is a pop spin node with activation animated one. I also animated the angular speed just for fun.
