The other option that allows a good combination of transformation and graphics - would be:

a. A shadow thrown on a wall - particularly if using a flickering light source like a candle/lantern.

b. Possibly shooting through dirty pane of glass/window or distorted glass shape/jar - depending on perspective.

You could start with certain elements, switch to something else (or possibly passage of time (sleep) + reveal), and then show a conventional transformation again. It would definitely be unique to mix up the types of visuals (maybe farming work out to different people with different skillsets and lessening the overall workload on individuals).
