Ventana Project is a curatorial initiative that transforms a former information cabin on the Alt-Tempelhof U-Bahn platform into a month-long exhibition space — a glass vitrine encountered by passengers in the flow of daily transit. For this installation, the showcase becomes a contained ecosystem, a world visible from the platform but held apart from it.

Hemitrichia serpula, the pretzel slime mold, builds networks of tube-like threads to navigate, feed, and reproduce — demonstrating distributed intelligence without a nervous system, without hierarchy, without a centre. These patterns echo structures found at entirely different scales: the branching of blood vessels, the filaments connecting galaxies. The micro and the macro rhyming across space.

The installation materializes this logic in algae biopolymer dyed with turmeric — suspended sheets of golden network cascading from above and spreading across the floor, sensors embedded beneath activating in response to the environment. The warm light they emit transforms the vitrine into something between a scientific specimen and a living organism, legible to passengers in passing and to those who stop to look closely.

Hemitrichia asks what intelligence looks like without hierarchy — and what we might learn from organisms that have been solving problems far longer than we have.
