"Kindergarten" was designed to create a narrative environment (children and monsters playing hide-and-seek at the fun fair) where the user is immerged and guided by a sound navigation through shapes and pieces of pictures. The installation consists of three visual and sound environments that represent the world fantasized over the funfair: the ghost-train, the distorting mirrors, and the peeping-hole. The web version is the light version and allows to interact with the ghost-train stage. The user moves in four directions (up, down, right, left) by means of the corresponding arrows of the keyboard. It is the sound and the music that take turns to drive the user towards the various environments, separated among them by screens of masks and shadows.
