16th Puchon International Fantastic Film Festival (PiFan) Launches a Teaser Trailer

Things are starting to heat up for the 16th Puchon International Fantastic Film Festival (which will be taking place July 19-29) now that a brand new teaser trailer has been released. It's a well-designed and whimsical little montage but does not give any hints as to what may feature in the lineup. However, included is an image of a QR Code and I'm curious to see how these will be integrated into the festival. Will they be used for the tickets or do they have something else up their sleeve?
