This is a tool I made for artists working in Unreal. It quickly allows artists to drag and drop animation points onto 3d assets. It has a few different animation algorithms they can choose from. That way with just a few mouse clicks they can have an object in the scene and animating actively.

Created in Unreal 4.

This tool allows a person to place a spline. Then they can put points along the spline to specify the curve. Then I exposed a dropdown of different algorithm types. They can also specify a mesh and a delay. It would be easy to add a trigger to delay the animation until an event.
