Heat Mapping Entropy is an interactive installation that synthesizes heat and light to visualize energetic disorder and stochastic data. The work engages with entropy as defined in physics and information theory, examining how energy disperses and how information emerges and degrades within dynamic systems.


A tactile metal surface embedded with temperature sensors responds to touch, body heat, or a heat stylus, influencing a surrounding LED matrix. Localized heat creates temporary zones of low entropy, visualized as concentrated hotspots that slowly drift and diffuse. Over time, these hotspots fade as energy spreads, reflecting the natural tendency of systems to move toward equilibrium.


The LED matrix functions as a noisy channel: motion, fading, and overlapping light introduce controlled noise that transforms sensor data into legible patterns, revealing entropy as a continuous negotiation between order and disorder.
