@joncipriano indeed it is a unique card. I think it has a lot of potential! We are hoping to tightly integrate Picapol with social media networks so users can express their opinions graphically amongst friends. If we were able to incorporate an iframe into a custom card with tailored html to fit within tweets: https://www.picapol.com/poll/412/embedh it would allow twitter users to vote without ever leaving twitter. That is ultimately what we are trying to achieve 
We will stay tuned and continue building so we are ready when/if new features come along. For now, we do have a few summary cards working and it’s nice to at least show the image on the card, but we do think some custom card to integrate our iframes would be a huge benefit for true integration.
Thanks again for your quick responses.
