Underware exhibition at Print Gallery Tokyo
April 2025

What if writing could be experienced not just visually, but physically and sonically, too? In Sensorium Motorium, Underware introduces a new kind of writing instrument – playful, experimental, and rooted in cybernetic theory.

In his essay Cybernetics of Epistemology, Austrian-American scientist Heinz von Foerster (1911 – 2002) introduces two foundational propositions for the acquisition of knowledge, grounded in the interplay between the sensorium (the system of conscious sensations) and the motorium (the regulated sequence of motion):
1. The meaning of the signals from the sensorium is determined by the motorium; and the meaning of the signals from the motorium is determined by the sensorium.
2. The laws of physics – the so-called “laws of nature” – can be described by us. But the laws of brain function – or, more broadly, the laws of biology – must be formulated in such a way that the act of writing them is itself derivable from them. In other words, they must be self-writing.

A few years earlier, von Foerster conducted the research project Mechanisms of the Perception of and Formation of Internal Representations of the Spatial Fourth Dimension (1971/72) with student Phyllis Arnold at the Biological Computer Laboratory in Illinois, USA. This experiment was motivated by the belief that dimensions higher than three could serve as an ideal means to separate newly assimilated information from past experiences. In doing so, participants might encounter a moment of pure understanding – understanding understanding, as von Foerster called it.

Sensorium Motorium
With Sensorium Motorium, Underware builds upon this historical body of research and connects it to the cultural domain of writing and sign-making. To explore this intersection, they developed a new, higher-dimensional writing instrument: the Fluxographer.

This multi-sensory grammatographic device enables the writing and experiencing of higher-dimensional signs through the simultaneous integration of haptic, auditory, and visual stimuli. More than a speculative tool, the Fluxographer offers a reflection on writing itself – how we write, how we read, and how the act of writing shapes perception and thought.

At the same time, it was also created with a playful spirit: an instrument designed to invite curiosity and joy. Something to explore, to try, to play with. Visitors are encouraged to interact with the Fluxographer – to write, to listen, to feel. The experience is as much intuitive and sensory as it is conceptual. Sensorium Motorium at Print Gallery Tokyo marks the world premiere of this new instrument.

The Fluxographer
The Fluxographer consists of a high-resolution touchpad device with a custom keyboard layout, the higher-dimensional typeface Flux (recipient of the TDC Tokyo Award 2025), an MPE (MIDI Polyphonic Expression) synthesizer, and a bespoke tool that connects all three into one coherent, multi-sensory system. The Fluxographer captures users’ gestures with precision and renders them into higher-dimensional forms – both visual and sonic. The exhibition also features a series of unique A0 Fluxograms (created using the Fluxographer).

This is Underware’s second solo exhibition at Print Gallery in Tokyo. Parallel to Sensorium Motorium, their award-winning project Flux is also on view at the ginza graphic gallery in Tokyo.
