In 2004 Rafael Lozano-Hemmer visited the university of Lincoln and gave a lecture for the architecture students on his past projects, and unveiled his latest project entitled UNDER SCAN. Under scan was then installed on the university campus. Using some high tech projectors a large space was flooded with light. Users interacted with the piece by walking within the space, their shadows blocked out the intense white light to reveal video sequences of individuals laying on the ground. As the user revealed them the video portraits would come to life and interact with the viewer. As the user walked away the video portrait would loose interest and return to it's original dormant position.
Another piece that interested me formed part of ARS electronica in Linz, entitled: DISPLACED EMPERORS.
Displaced Emperors was an installation that used an “architact” interface to transform the Habsburg Castle in Linz, Austria. Wireless 3D sensors calculated where participants pointed to on the façade and a large animated projection of a hand was shown at that location. As people on the street "caressed" the building, they could reveal the interiors of the Habsburg residence in Mexico City, Castillo de Chapultepec. In addition, for ten schillings, people could press the "Moctezuma button" and trigger a temporary post-colonial override consisting of a huge image of the Aztec head-dress that is kept at the Museum für Völkerkunde in Vienna, followed by a parade of images of jewels from the Austrian-Hungarian Empire, set to music by Toña la Negra.
Details of all of Rafael's work can be found on his website.
