This ‘museum’ has no fixed location, no entry or exit, no tickets, no donors or board of members. Its temporary collection is the unfinished city, temporary project, imperfect idea or juvenile plants in propagation from seed, awaiting spring. The permanent collection are the so-called spheres; bio, hydro, litho, atmo and techno. A deep-time tiramisu enfolding highways and regional infrastructures thanks to which we orchestrate our contemporary lives. The two are in a constant state of flux.
