YinYang Clock

A clock that keeps track of time spent yinning vs time spent yanging.

Features

It's basically just a bidirectional stopwatch, each time you click it the current side is paused and the other side is resumed.
A Ctrl/Cmd+Click or a triple tap can be used to reset the clock.
Appending ?midnight to the url will switch to mightnight-mode, where the clock is anchored to the last midnight: it resets automatically at midnight and the yang side atomatically starts from there. Resetting the clock will be necessary to see a change.
Appending ?minimal to the url will switch to minimal-mode, where the clock is not rendered but only the background rectangles are.
Appending ?amoled to the url will switch to amoled-mode, where only a line is rendered and most of the app is pure black.
