Barkeno is an audiovisual performance using our installation Barcelona as a visual instrument and set of traditional and experimental musical instruments.
Barcelona is an interactive installation and visual instrument. Its interest resides not only in its aesthetic proposal, but also in that it shows how media appropriation allows artists to reclaim and re-signify the technological production while reflecting on the relationship between DIY practices and state-of-the-art technologies.
The piece consists on a two–meter tall Pentakis dodecahedron, with each edge independently lit using LED strips. The installation can react to both to its environment – it senses movements and sounds produced on its vicinity – and to the performers using different controllers we have developed.
All the hardware in Barcelona is of the artist’s authorship. Moreover, every functional component is visible and contributes to its appearance. However, the cabling within the dodecahedron is concealed. Spectators can follow the data path from the controllers to the piece, but not inside of the structure, allowing for an organic perception of the piece.
We use twelve 8xLED drivers designed by us, located on a table at the bottom of the dodecahedron. Ninety cables connect the drivers to every edge of the polyhedron.
The structure consists of PVC pipes of two different lengths with 3D-printed joints that allow for its rapid assembly. On each edge there is a RGB LED strip surrounded by a cylindrical diffuser.
