The PS4-Pong example in the README has a YouTube video[1] so it's physically possible to run something with the HTML5 canvas renderer, but there doesn't seem to be much in the way of instructions to do so up there.

As for the sparseness, definitely true, the SDK really doesn't have much in the way of functionality yet, but I'm kind of surprised by what they have so far.

There are no instructions because the code exec method is not (yet?) public. The exploit is, but not the payload to run applications. There is no announced release date for code exec method, or indeed announced plans to release, as far as I am aware.
