I'm struggling to find an example of an HTML5 VAST/VPAID ad. IAB's VPAID spec doesn't include a good example on how to use the JavaScript VPAID APIs.
Answering my own question since I think this will be useful for others.
You can find a bunch of JS VPAID ad examples here: https://github.com/ryanthompson591/vpaidExamples/
If you need the VAST tags, you can get them from here: http://ryanthompson591.github.io/vpaidExamples/
