A Cyanometer is an instrument used to measure the blueness of the sky. It was invented by Horace Benedict de Saussure in 1789, a Swiss physicist interested in the geology, physics and topography of the Alps region. His work helped popularize Alpine tourism and alpinism.

This project is a large open-air intervention in the form of a monolith set against the sky. By using innovative technology, this version of cyanometer will retrieve information from the sky in order to make it visible for anyone who stands in front of the structure. The idea is to install several interconnected cyanometers in different areas.

The monolith will have three separate LCD screens: the highest third of it will function as a cyanometer showing the blueness of the sky in short time intervals. The second third will show information collected from other installations; apart from blueness it will show the temperature, current weather conditions and air pollution. The third and lowest LCD will be a touch screen for public interactivity. This screen could display information about the natural and/or cultural heritage of the place.

By creating a large interactive public artwork, the aim of the project is to research and showcase what a contemporary landmark could potentially be.
