Just using a simple square and circle I tried to fit in as many of Jorge's 10 principles as I could. I'm still playing around with AE and figuring out the best ways to manipulate the shapes in the ways I want. Of the 10 principles the ones I managed to use are Timing, Spacing and Rhythm, Eases, Mass and Weight, Anticipation, Arcs, Squash, Stretch and Smears, and Secondary or Layered Animation. I don't think I really managed to utilise the remaining three (Follow Through and Overlapping Action, Exaggeration, and Appeal) very well.
