'After looking over a few websites I got looking at some Rafael Lozano-Hemmer work and I must admit I would love to find out where they get all the money to pay for all there works and installations, as they can't be cheap!
These two works caught my attention particularly:
'Pulse Park is comprised of a matrix of light beams that graze the central oval field of Madison Square Park. Their intensity is entirely modulated by a sensor that measures the heart rate of participants and the resulting effect is the visualization of vital signs, arguably our most symbolic biometric, in an urban scale.
In Pulse Park, evening visitors to Madison Square Park have their systolic and diastolic activity measured by a sensor sculpture installed at the North end of the Oval Lawn. These biometric rhythms are translated and projected as pulses of narrow-beam light that will move sequentially down rows of spotlights placed along the perimeter of the lawn as each consecutive participant makes contact with the sensor. The result is a poetic expression of our vital signs, transforming the public space into a fleeting architecture of light and movement.
Pulse Park is inspired by Roberto Gavald√≥n‚Äôs film ‚ÄúMacario‚Äù (Mexico, 1960) in which the protagonist has a hunger-induced hallucination wherein individuals are represented by lit candles, as well as by the minimalist musical compositions of Conlon Nancarrow, Glenn Branca and Steve Riech. Pulse Park is the culmination of a series that Lozano-Hemmer debuted at the 2007 Venice Biennale with Pulse Room.'
I really like this as it utilises public interaction really well and is a great way to represent our 'vital signs'. I am sure this would look incredible to the viewer as well and would give the environment a human like sense of life. Check out this video to see it in action.
'Voz Alta (Loud Voice) is a memorial commissioned for the 40th anniversary of the student massacre in Tlatelolco, which took place on October 2nd 1968. In the piece, participants speak freely into a megaphone placed on the "Plaza de las Tres Culturas", right where the massacre took place. As the megaphone amplifies the voice, a 10kW searchlight automatically "beams" the voice as a sequence of flashes: if the voice is silent the light is off and as it gets louder so does the light's brightness. As the searchlight beam hits the top of the building of the Ministry of Foreign Affairs, now Centro Cultural Tlatelolco, it is relayed by three additional searchlights, one pointed to the north, one to the southeast towards Z√≥calo Square and one to the southwest towards the Monument to the Revolution. Depending on the weather, the searchlights could be seen from a 15Km radius, quietly transmitting the voice of the participants over Mexico City. Anyone around the city could tune into 96.1FM Radio UNAM to listen in live to what the lights were saying.
When no one was participanting the light on the Plaza was off but the three lights on the building played back archival recordings of survivors, interviews with intellectuals and politicians, music from 1968 and radio art pieces commissioned by Radio UNAM. In this way the memory of the event was mixed with live participation.
Thousands of people participated in this project, without censorship or moderation. Participation included statements from survivors, street poetry, shout-outs, ad hoc art performaces, marriage proposals, calls for protest and more.'
This was a great idea and personally the first 'interactive' memorial I have ever really seen. The ability for the users to talk over the megaphone to make their points and express their thoughts and feelings is a nice touch yet essential to the piece. I also like the fact the light is relayed to the top of the building which then sends out the message via flashes in 3 different directions over the city, almost as if it is showing free speech with the visible light beam going up the building clear to everyone like it is proving it is not controlled by a higher government or agency corporation.
