Other Options

Promotion Animation - Look in your calendar and select an upcoming event / club / school initiative / good cause / special day (think Google's special logos) to promote. Create a short animation that promotes this that can be used closer to the event or throughout the year. Make sure to include textual information to explain further what the animation is for.

Logo / Upcoming Events Animation - Create a animation of the school logo or your own version of an AY Jackson logo. Imagine this being displayed on the screen every so often. Make it very unique and eye catching. 

Designer's Choice - Have a really good idea that doesn't fit into one of these areas. Write it up with some quick storyboard ideas and submit to your teacher for approval.
