The squid’s body surface has unique cells which contain a pigment called chromatophores.

We stimulated the chromatophores of squid by sending sound signals of accompanied music to its body through electronic probes and made an experimental music video/performance.

In contrast with the standard displays, our display only exists in a specific location and time because of the requirement of freshness. However, the limitation proposes the geographical variation of displays according to the different types of squids. In this sense, the squid display is a video output device made in the ocean. Thus, the decrease of biodiversity directly means the reduction of visual expressions.

The idea of Umwelt [Uexküll, 1934] leads that animal consciousness cannot be returned to objective science. Squid is said to have a sense of sound through the skin. Also, since the structure of the photoreceptor in the retina of the squid is different from humans, it is speculated that squids perceive a different world from us  [Godfrey-Smith, 2016]. However, if we could moderate (e.g., refrigerated) their movement alive (currently, we assassinate them to fix the body), we might interweave our message (i.e., sound signals) with the primal pattern generated by squids.

The squid display is an attempt to visualize a piece of music as an electric signal. In the same time, our approach also highlights the common points that all species use an electrical signal for communication.
