The webpage describes an interactive installation called "My little piece of Privacy" by artist Niklas Roy. The setup features a smart curtain in a storefront window that moves with the pedestrians outside, utilizing surveillance technology, a laptop, and a motor to position the curtain accurately. Despite the objective of creating privacy, the moving curtain attracts more attention, leading to a paradox; the existence of the curtain itself subverts the intended privacy. A larger, faster, and more flexible second version of this installation was developed in 2011, with significant improvements including a more powerful drive and updated computer vision software.
The jerky movement of this curtain is making me lol (hard)…Niklas Roy: My little piece of Privacy
