At Ñuñoa station in Santiago, where Line 3 meets Line 6, commuters change trains three levels underground. Since Thursday 8 October 2026 they have been changing trains inside H.R. Giger’s biomechanics. Alien: El Origen fills Suizspacio on level -3, runs until 31 December, and costs nothing beyond the metro fare. As Francisca Bórquez reported for Radio Agricultura on 15 October, the show is organised by Flashpoint Producciones and the Swiss Embassy with the HR Giger Museum in Gruyères, under the curatorial supervision of Carlos Arenas. The museum calls it its first authorised exhibition in South America.

Ambassador Charlotte Bleisch framed it simply: «Esta muestra nos permite mostrar otra faceta de Suiza», another facet of Switzerland. Felipe Bravo, Metro’s general manager, called it «una nueva expresión de la estrecha colaboración» with the embassy, a partnership that has run at Suizspacio since 2019. One question is worth carrying down the escalator: what does a person see when they did not set out to look? A transfer level is a place of divided attention. Here, Giger arrives inside a commute, not a pilgrimage.

Giger was born in Chur in 1940 and died in Zürich in 2014. He moved to Zürich in 1962 and studied architecture and industrial design at the School of Applied Arts. In 1980 he shared the Academy Award for Best Visual Effects for Alien. His biomechanics, flesh and machine read as one continuous surface, shaped the look that cyberpunk later took for granted. The quieter work deserves its name too: Carmen Maria Scheifele Giger directs the museum at the Château St-Germain, and shows like this one travel because she and Arenas’s team do the slow work of loans, crates and permissions.

Rooms, not pictures

For an architect, the essence is that Giger did not stop at the canvas. The Giger Bar Kalchbühl in Chur opened on 8 February 1992. Chur Tourismus records that it was first planned for New York, and that the entire interior, bar and furniture included, is his. In Gruyères, the Museum Bar opened on 12 April 2003, with roof, walls, fittings and chairs modelled by the artist. Fribourg Région describes it as «a sort of cave with arches made of vertebrae».

Read that sentence as a structural drawing. A ribbed vault is one module repeated along a curve, the logic Gothic masons used to turn a single templated rib into a nave. Giger kept the logic and changed the skin: the rib becomes a vertebra, and the repetition becomes a spine you sit inside. PAZ has followed the same thread from the structural side in our hanging-chain piece on form-finding from Gaudí to RhinoVAULT. The trade-off is plain: a module that scales or twists along its curve looks alive, but every distinct rib size is another mould, another CNC path, another line on the Bauleitung’s list.

←TODAY: A Swiss artist trained in architecture is shown free, three levels under Santiago, until 31 December 2026.
→3012: Zurich’s transit halls are grown from one rib module per line, each station a variation on a graph.
Fulcrum: The vault of vertebrae is a parametric array drawn by hand, decades before the slider existed.

Atelier: Offices now asking an AI assistant to propose ornament or structure face the same question Giger answered by hand: how many distinct parts does the beautiful version cost? Monday move: add one line to your office’s fabrication checklist, “count the unique rib sizes before the array leaves Grasshopper”, and make it a sign-off condition.

Hack: Array one bone-like rib along a path curve and let two numbers grow and twist it. In a GhPython component inside Rhino + Grasshopper, feed a path curve, a rib curve drawn on the World XY plane, a count n, a twist angle in radians and a growth factor. Each rib is placed on a perpendicular frame of the path, scaled first, rotated second, then moved into place.

import Rhino.Geometry as rg
ts = path.DivideByCount(n, True)
frames = [path.PerpendicularFrameAt(t)[1] for t in ts]
a = [rib.DuplicateCurve() for f in frames]
for i, (c, f) in enumerate(zip(a, frames)): c.Transform(rg.Transform.PlaneToPlane(rg.Plane.WorldXY, f) * rg.Transform.Rotation(twist * i / n, rg.Vector3d.ZAxis, rg.Point3d.Origin) * rg.Transform.Scale(rg.Point3d.Origin, 1 + grow * i / n))

Replace the linear i / n with a Graph Mapper output and the vault starts to breathe; loft output a to see the skin.

Spaces of transition

The follow-up comes home. H.R. Giger: Der Weg des Magiers (Passagen) opens at Photobastei 2.0, Sihlquai 125 in Zürich, from 12 to 29 November, directed by Romano Zerbini. Its four-part group Passagen – Tempel is described as «monumentale Übergangsräume»: monumental spaces of transition between birth and death, technology and body. A metro transfer level is an Übergangsraum too. Giger simply made the passage visible.

Model one rib, array it along a curve, and before you loft it, count how many different ribs your graph just asked someone to build.
