(CNN) -- The annual San Diego Comic-Con, North America's biggest popular arts convention, is a gathering of fans and celebrities from all over the world.
Micro-video apps like Vine and Instagram were everywhere this year at the convention, and CNN iReporters took on the challenge of doing 15-second interviews with interesting people -- both famous and not-so-famous -- that they ran into during the long weekend.
The results, though not always exactly 15 seconds, were a snapshot of the many varying events and people who populate the Con each year.
From fans celebrating their favorite shows on Syfy, to the ever-growing phenomenon of cosplay, to the stars of the TV series "Impractical Jokers" talking about their favorite practical joke, Jack Black's cape, unusual hats, and yes, Teenage Mutant Ninja Turtle stalking, here's a quick look at how the Con has evolved into a smorgasbord of pop culture.
