When I was at Magic Kingdom, I saw some people in front of a store front pointing their phone or something at a thing in the window and it triggered some type of little video clue. Looked like a clue on a scavenger hunt. Quick! Someone clue me in!! What is it and how can I do it when I go back?!?! 
That sounds like it's the Sorcerers of the Magic Kingdom. DH and I have never played it, but we've seen people playing it each time we've been to MK.

Thanks 
I fancy having a go at this but I don't think my kids are old enough to be bothered with it!
If it's not "the dancing dollies" or "Buzz" it's hard to get them to do anything else!

It was probably Sorcerers of the Magic Kingdom! Here are some articles we wrote when the game first debuted. It's fun!

There is also A Pirate's Adventure in Adventureland
Another interactive game to check out at Magic Kingdom is Pirate Adventure. The concept is similar--follow a map and uncover clues to follow the story. It's only in Adventureland, so it doesn't send you all over the park for the next adventure. Also, the things that you uncover have live events instead of events on a screen. We also found the map and clues to be easier to read and follow. The sign-up station is between Adventureland and Fontierland inside of a small building. It's easy to miss it.

Socerers of the Magic Kingdom is an awesome game but it takes up a ton of time depending on how much you want to do. You can sign up at the Fire Station on Main Street or behind the Ye Old Christmas Shoppe in Liberty Square. You get a pack of cards each day you play. Each card has a different spell on it that is associated with a Disney Character. Like Flynn Ryder has the flying frying pans as his spell. Each spell is characterized into hero, warrior, animal, toy, princess, mystic and machine. There are 60 cards you can get for free. Part of the fun is trying to collect all of the cards. The first 22 (star cards) are the hardest to get and each pack comes with one star card. The game is in Main Street, Adventureland, Fantasyland and Liberty Square/Frontierland. You can also buy booster packs which come with a board game to play at home and a pack of cards. The pack comes with a lightning bolt card and the regular pack you would get for playing that day. When you defeat the game as a whole, you can get a another pack that day for defeating the game. Once you defeat the game you can either level up or stay at the same level. They also have shirts you can buy to get a booster each time you play.

We took part in a couple of these last trip. It was pretty good, a scaled down hunt because it only in the one long. The actual interactive treasure clues are very well done and entertaining.

I played one round the other day and it was really fun! I started it late in the day so I couldn't do more, but I think it's definitely worth doing if you have more than one day at MK
I've wanted to try this. I'm a big rpg nerd, and while I haven't got into the collectible card games the way many of my peers have, there is something about assembling a deck that does speak to me on a primal level. For instance, from a game play standpoint, my favorite game in the Kingdom Hearts franchise is Re: Chain of Memories, as each play through I discover a new trick with the card mechanic in that game. I'm surprised that Square Enix hasn't made an online multi-player version, as that would be awesome.
But anyway, yeah, I think I definitely need to try Sorcerers of the Magic Kingdom on my next visit.
