Photo/selfie/messaging sharing system

Hi all,

I remember 'back-in-the-day' that quite a lot of club and bar venues had systems where you could take a photo and send it to a screen within the venue. Messages as well. I'm thinking this would be a cool thing to have as an extra for my mobile DJ gear, and wondered if anyone knows of any systems that do this, or has experience? Ideally you could collect the photos and provide them to the customer after the gig (make great marketing material as well, with permission of course).

Any guidance much appreciated!
