Interactive exhibit at “Das Netz” in the “Deutsches Technikmuseum Berlin” – cooperation with Felix Scharstein
This device shows a network of 18 nodes and 27 edges that form a model of the internet. Messages can be send betweeen 4 terminals. These messages are split into data packets that are reassembled at the receiving terminal. The routing of the packets depends on the different base speed of the connections and the current network load. Nodes (routers) can be disabled to simulate network outages.
The data flow is visualized using flip-dots (mechanical bistable display elements). A high load on the network can be experienced as a real motion with an acoustical effect.
The whole exhibit is covered under a glass panel, all 30 buttons are touch-sensitive capacitive elements.
