It's like a normal tabletop rpg, but at the same time it needs a projector and wifi to really work. I've considered asking the panel staff but I thought I'd start here to gauge interest.
The game is called
PICSPAM ADVENTURE.
I have an online database with a collection of pictures. Each picture is a person, place, object, creature, or action. Your character is a randomly selected combination of a person, an action, and an object arrangd by using your smart phone or tablet to open the character generator here:

The party visits 5 random encounter over the course of the adventure and the GM moderates the whole thing by fitting together the random elements into a loose story. I personally like to use a a d20 to decide things. The whole game can be seen online here:

Now, I could always just sign up for a table at the game room and have people huddle around my laptop to see the encounters. I can't help but think it would be way more fun to have a panel room with a projector to display the encounters and then draw people from the crowd to play with the characters generated on their phones. The randomness of the game makes it a better spectator sport than normal rpg sessions.
So if there's enough interest, I'll fill out a panel form and try and get a room. Otherwise, look me up at the game room some time.
