In the middle of the covid pandemics, I order a light design company online to produce a customised gobo (1) for me representing a computer isohedral tiling pattern (2), visually close to the kind of sea or wave gobos traditionally used on theatre and opera stages. One evening in March, from the balcony of my apartment, I project the pattern on the surface of the Baltic Sea in the melting, with a profile projector equipped with the gobo (left image), as a remote performance for the site-sensitive show which takes place approximately 11 kilometers away from my place, and where the gobo pattern is projected, randomly and in a small scale, by the works of the other artists (e.g. on the image on the right, by Sari Palosaari's take off).

(1) A gobo, whose abbreviation derives from the English goes before optics, is a metal plate placed in front of a projector, on which a pattern is cut, most often with laser ablation techniques. It is used to give a shape to a light that is cast over a space or an object, for example, to produce a pattern of clouds on a theatre stage.
(2) Isohedral tiling is a category of computational tiling used in computer graphics in the contexts of texture generation, remeshing, and the generation of decorative patterns.
