Thermochromic Painting.

The surface of the painting is coated in thermochromic pigment, which is black at ambient temperature and becomes transparent when heated.

Three resistive wires are shaped into an engraved sheet of Perspex, forming the perimeters of three famous Italian domes (San Pietro and Sant’Ivo alla Sapienza in Rome and Santa Maria della Salute in Venice). These are then connected to a battery through three buttons that interrupt the circuit.

Once the buttons are pressed the energy flows and heats the resistive wires, which are placed directly behind the thermochromic ink layer, heating the pigment and thus changing its color.

An experimentation with Flexion, shape changing wire that retracts when heated (thus when connected to 9v battery in this case). A button completes the circuit: when the butto is pressed, the wire is heated, it retracts, and pulls the box lid.

This laser-cut copper conductive fabric snake works as a speaker when connected to an amplifier and brought close to a magnetic source which amplifies the vibrations generating the music.
