Prezi has 3D boxes made from cubes arranged like a spiral, an illustration where cube assembling from blocks. Above the illustration is a shadow which makes a feeling like 3D cubes are flowing on air. 3D Boxes are separate elements and can be moved, resized. Zoom in and quality of the box remains great because all shapes are vector based.
Mixing music is a good template for creating a music related presentation with a smooth flow of slides. Prezi has the vintage classic vinyl record with circular animation and Sound Mixer Console.
