At the first moment, it is hard to say what is this, but the
real hacker can tell what time it displays
So it is the clock for the real hacker, as not everyone can read
its time.
Some bugs are periodically simulated, so those waveforms
whistle, curl, curve, warp, then for a moment write the decimal
numbers ... and even in plain text. Just enough to confuse
observers, and then again return to "those awful waveforms."
In the same time, the colour of the environment is also changed,
so this clock is never in the steady state. It is actually a
story about the hardware.
