Your circle can be a real-life subject ie. a golf ball, or a hole in something, you can decorate/embellish your circle, it can have a personality/identity, it can start abstract too, and there can be more than one circle...
But no matter what, you should create a simple story about your circle: establish the character through graphics and motion, give some conflict, and have the conflict resolve.
- Create a Symbol/main character [AKA Circle].*
- Background on a different layer to establish scene.*
- Must include a short narrative: Establish character/conflict/resolution. *
- Frame to frame animation
- Motion Tween
- Classical Tween
- Transform
- Scale Tween
- Colour Effect Tween
- Shape Tween
- Ease
- [You can animate the background too.]
