You turn on your computer and boot it up. You are going to the halfbakery.
You want to test your new keyboard. Your thermochromatic keyboard.
You place your fingers on the keys.
Slowly, the keys begin to warm up from your finger's warmth.
As you hold your fingers, the keyboard changes color
where you are touching it.
Starting at black, progressing through the colors, from the cool blues to the greens, to the reds, and at last to the yellows.
You remove your hands and wait.
The keyboard cools.
The colors now start progressing backwards.
When the keyboard is lack again, you start to type your new idea.
