Institute for the Future teamed up with Sun Microsystems and Boing Boing Video to co-host the Digital Open, an online tech expo for teens 17 and under around the world.

We're publishing an 8-part series of videos profiling the winners. Today, meet 16 year old Harry Lee of Melbourne Australia. He talks with us about his "Sneaky Card" game concept, which explores social interactions between people. He was inspired by ARG and indie projects like "Bite Me," by Gamelab, and Jane McGonigal's Top Secret Dance-Off, both of which we've covered previously on Boing Boing.

"I love index cards," says Harry, "And I was thinking — hmm, how can I incorporate them into a project?" So he designed and printed these game cards, and "spread the seeds of sneakiness and espionage" into the unsuspecting pockets, math books, binders and bags and jackets of his schoolmates.

I tracked most of the cards and found, with much satisfaction, that a majority of them had been passed down at least three times. The most successful story is of the card passed from student to student three times before ending up in a math teacher's jacket. The teacher found it and gave it to another math teacher, who inserted it into a student's corrected test before giving it back to him. The card passed hands once again before I lost track of it.

Below, some sample cards in Harry's game. (Link to PDF). More after the jump.
