I while back I posted about a slide deck type presentation site (Polymer Slideshow) I was working on with Polymer. Today I posted it up for the world to see.
The controls are simple. You can use your arrow keys for Left, Right, Up and Down, as the guide highlights the availability of those options. Pressing the Spacebar will trigger the next action, whether it be to fire a subelement or to fire the next slide. Although come to think of it, I don't actually have an onscreen triggerable event to set of a next option. So I will make an issue for that to be fixed on the GitHub Repo for the project.
Check it out, let me know what you think.
