Feedback is an interactive installation that aims to encourage performance from members of the public and circus performers alike. Using the familiar form of a mirror, the installation uses cutting-edge computer vision techniques to allow users to remix their bodies in real time, and display them on a large scale over the interior and exterior of the Roundhouse in Camden.

By dancing, performing – or even modestly gesturing in front of the screen – the installation will capture the movement of anyone interacting with it to create a graphic animation of their body movements. The effect is similar to that of a ‘Hall of Mirrors’, generating an unexpected and magical wobbly, bendy or stretched reflection.

The LAPP is a one-shot long time bulb exposure Photography, performed additionally with movement of light. LAPP originates on a real-time basis directly in front of the camera. Created between opening and closing the shutter. LAPP is descended from light drawing and has been developed in its own art form. As the evolution of light drawing, it is complemented with additional elements in the form of light figures, colors and light-forms to create such a special view.

The LAPP images are made by Jan Wöllert and Jörg Miedza,from Bremen, Germany. They have been working together since 2007 but neither are full-time photographers.
