This installation by Pablo Valbuena is called Augmented Sculpture v1.0. I don’t think words can convey the fascinating effect of this installation of light, so better watch the video above. :)
This is one of my favorite installations. I have seen it in reality (at Ars Electronica 2007) and it was at least equally fascinating and beautiful there as in the video. The setup at the Ars Electronica Festival had a more mysterious atmosphere, because it was placed in a very dark, old, room which had the feeling of a ruin.
At the website of Pablo there are more beautiful pictures of the installation, the same video in better quality, as well as the artist’s description:
This project is focused on the temporary quality of space, investigating space-time not only as a three dimensional environment, but as space in transformation.
