Set a timer or alarm for any point in the future but not beyond the year 9999. Cesium will then ceaselessly count down every second, minute, hour, day, and year until the job is done.
A timer is utilized traditionally to track the time when cooking or baking or—in some social circles—torturing. The common kitchen timer ticks for a while and dings at its conclusion. That's not exactly exciting, even if it dings more than once. Cesium, on the other hand, has both visual and auditory alarms. When you lose a "patient" in the basement, you can no longer say, "Boss, I didn't hear no timer."
Red is the color of danger, the color that attracts the most attention, the color of raspberry jam. In those crucial final moments of a countdown Cesium will brighten gradually into a passionate, alluring, seductive, alarming red. If you stare too long, it'll stare back into you.
I use Cesium for captcha wait times, the ones that are crazy long like 5 minutes. Too many times I'd switch to another browser tab, forget, and return to an expired session. Really, forgetting is the ultimate human verification, but I digress. With Cesium I never miss my window of opportunity!
Cesium oozes pure class. It just looks so classy. It's like a piece of art in a "look but don't touch" museum. But I get to touch it and play with it!
