Developer plans to create a fluid simulation on a large flip-dot display for EMF2026

Project Overview

A developer is creating an installation for the EMF2026 event, which will feature a fluid simulation rendered on a large flip-dot display. The primary motivation for using flip-dots is their electromechanical nature, which produces audible 'swishing' noises, adding a sensory dimension that LED-based liquid simulations lack.

Challenges with Flip-Dot Displays

Flip-dot displays are noted for their high cost and limited availability. There is reportedly only one manufacturer still producing them, with exclusive deals that make them inaccessible for projects with smaller budgets. Previous attempts to use existing displays were unsuccessful due to cost and owner reluctance.

Sourcing and Technical Details

The developer eventually acquired a large quantity of old flip-dot displays from Sam, known as Look Mum No Computer, who runs a museum of obsolete technology. These units, possibly reclaimed from old buses or new-old-stock, are in varying conditions. Flip-dots are non-volatile, maintaining their state without continuous power, using two permanent magnets and two polarizable cores to set their position.

Potential Impact

The developer expressed a hope that publishing details of this project might inspire companies, particularly in China, to produce more affordable flip-dot displays, thereby increasing their accessibility for future projects and installations.
