"Fold Loud" by JooYoun Paek merges the ancient art of origami with digital music control to create a calming interface for sound -

Playing Fold Loud involves folding origami shapes to create soothing harmonic vocal sounds. Each fold is assigned to a different human vocal sound so that combinations of folds create harmonies. Users can fold multiple Fold Loud sheets together to produce a chorus of voices. Opened circuits made out of conductive fabric are visibly stitched onto the sheets of paper which creates a meta-technological aesthetic. When the sheets are folded along crease lines, a circuit is closed like a switch. Thus, the interface guides participants to use repetitive delicate hand gestures such as flipping, pushing and creasing. Fold Loud invites users to slow down and reflect on different physical senses by crafting paper into both geometric origami objects and harmonic music.
