Hi! I'm going to be at PAX East this year but in a different capacity than last year. Instead of my own booth, I'm going to be demoing from within the SkreensTV booth. (right near the Twitch booth).
They're building technology that allows you to merge multiple screens onto one display, and it might be of great interest to Twitch streamers so Disco Dodgeball seemed like a pretty neat way to show off the tech.
In interest of disclosure, I'm not getting paid for demoing from their booth, but I am getting free both space out of it.
I'll have two laptops running, hooked up over LAN, and the video output will be broadcast and merged to a single TV. So it kind of turns it into a local multiplayer split-screen experience (although at the moment you still need a separate computer for each player).
Stop by and say hi if you're attending! Would love to meet some of you.
