Thermal Camera

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 464.8 Hz, 95 cents sharp of A4, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap to switch the thermal camera on or off, and watch the tea cool.

Everything gives off infrared light, more the warmer it is. A thermal camera measures that light and paints each temperature its own false color: here, black and violet for cold, then magenta, red, orange and yellow up to white for hot.

The tea in the mug starts at about 72 °C and cools (sped up: in real life it takes many minutes) as its steam thins. The mug's wall warms from the tea, the hand warmer stays at about 47 °C as the iron powder inside slowly rusts, and the glass of ice water is cold. The table is at room temperature, warmed or chilled a little where things stand on it. The scene and its temperatures are built for the splash.

Made in Splashery. Its code is MIT.
