It’s not here. It is not missing. v2 from Kjetil Austvoll-Dahlgren on Vimeo.

“It’s not here. It is not missing.” is an interactive installation exploring the negative space of perceived reality, seeking to sensitize the visitor to the subtracted parts of the whole.
It uses the metaphor of shadows as masks for visuals as well as sound.

It cycles through two states, a subtractive state and an additive state, complementing each other as two approaches to the same theme: the small parts that make up the whole. The subtractive state is meditative and subtle, while the additive state is brash and immediate.

The installation is built with Arduino (arduino.cc/) and Processing (processing.org/). The music is by Sindre Husebø.

The basic setup:
10 LDR’s (light dependent resistors)
2 arduinos
2 projectors (minimum)
1 computer (with a graphics card capable of running multiple screens)
Space -> The installation utilizes the room it is in, every setup is unique.
