Point fixe is an intervention in public space, dealing with control systems in urban space. Created during an artist-in-residency stay in Montpellier, the work directly refers to the city and its urban appearance by taking up the formal characteristic of certain signposts, translating them into a light installation. This characteristic, a coated backside reminding of a code, can be found all over the city, but rests, due to its position, mostly invisible. Point fixe inverts this invisibility in spotlighting the backside, turning it into a new information. Reconstructed as an illuminated sign and placed on the original signpost, the information on the back becomes a visible, communicating message, which, however, remains undecipherable.
