Get demos from the attendees

Would be cool to contact the attendees who presented demos and ask about providing links to the demos. We could use it for the testimonials/showcase section of the new site for the upcoming event.

I'd love to have as many demos as possible. Preferably the attendees copy their code in a Codepen and we can add a link to the end of the materials. Or at some point we create a page dedicated to attendee demos.
