What is "biowall"

The BioWall is a bio-inspired computing surface made of several thousand electronic modules which can be seen as artificial molecules. Each of these modules contains a programmable electronic circuit, a touch sensor and a display composed of 64 LEDs (Light-emitting diodes). As a result, each module enables the visitor to communicate with the surface by touching it with his finger, calculates its new status and indicates it immediately on a coloured display.
