Here is something fun from designers Sebas and Clim. Anicons is a series of animated icons available for Adobe After Effects for about 50 bucks. The fully customizable icon sets that are easy to use and modify. The icons are built as a library for motion designers, editors, or anyone else involved with the development of animation, and moving images. The icon sets feature a fun illustrative style, and fluid animations with bright color pallets. The best part is, you could probably use these as a starting point for your animation and swap out the graphics with your own illustrations to extend the sets.
