I have looked at multiple examples of similar things but nothing is suitable yet. Thanks Image included as example :

You can use Path Animations with MatrixTransform to achieve this motion. Depending on the content of your "Complex Path" you might then have multiple other StoryBoard's along the same animating path with different alpha values to thus give a trail effect.
