I’m mostly writing my own tools based in HTML5/Javascript.

In preparation, I’ve developed an vector animation tool (very work in progress) which I’ll be building on throughout the course of the competition.

My code repository can be found here:

Examples of the vector animation tool are posted in this gallery of animated gifs:
