Some try to sell things they don't need,

others celebrate the things they already have.

A Félix González-Torres clone elevates along a Riemann curvature. The clone shape-shifts to a curtain made from nanotechnology-based materials for cosmic dust collection. It is like a stretched hand of their senses, that extends their ability beyond the limitations of the body. Technology is relied upon to communicate and achieve what the body cannot — to go beyond, to go “outside” of oneself.  

Application of nanotechnology in cosmic dust collection makes it possible to shorten the maintenance and repair periods of collector devices, and thereby reduce maintenance costs. The technicans at the Welcome Habitat are experts in elevation and cosmic dust harvesting but also in technology impact assessment. But their main concern is the competitiveness of their companies in the cosmic dust collection sector. Their curtain dust collecting system harvests effectively and quickly all cosmic dust and dirt. Over time they transformed their bussines into a religious cult. 

The curtain presumes to reveal its subject but, in the end, the curtain is the subject-matter, it contains the meaning. The very fact that it conceals and reveals simultaneously gets at an essential truth at the heart of significance — the dwellers must think from both sides of the curtain. 

But when the curtain closes, the series of events become an object-like memory composed of a myriad of moments.
