The Moody Picture

Interactive Thermochromic Poster

"The Moody Picture" is a piece of critical design which explores the idea of generating design artefacts through alternative processes and medium to create a more innovative and surprising effect and to raise the viewer awareness and challenge the observer. The content of the poster is a critique to the role of fine art nowadays, whose content is often illusive and misleading, often lacking of concept and left to interpretation

It's role is also to challenge the expectations of its viewers and to raise awareness of the very current theme of surveillance.

The Process

I have drawn the two deterrent images first to then expose them on the screen and impress them on paper: the first image is printed with black ink; The second one, overlapped to the first one, is printed with thermochromic ink which, black at ambient temperature, becomes transparent when exposed to heat.

I designed a heating pad with resistive wire and Polymide film tape, able to resist very high temperatures. The heating pad is then connected to an Arduino which also controls an ultrasonic (distance) sensor. When the sensor detects a very close distance of the viewer to the poster, it releases a resistor that consequently lets the power flow till the heating pad.

The heating pad heats up, so the image printed with thermochromic ink becomes transparent and reveals the image underneath.
