# paukparl-clock

Brief:
I thought of a digital clock with each digit restlessly trying to stand still, while continuously having to offset external forces to stay balanced. I think such state is called dynamic stability. I was inspired by Jacob Tonski's Balance From Within. I used processing with geomerative and fisica libraries.

Rules:
1. Every time a digit needs to update, it disappears and falls again from a fixed position. Same rule when a digit goes out of bounds. This can cause some unexpected chain reactions in the following few seconds.
2. Each digit has an inherent "tremble" generated by noise. The digit would try to offset the torque by shifting its body left or right. But once it falls to its side, it will be hard to get back up again. Sadly, it will stay there until it needs update and a new number takes its place.

when the clock first turns on

some tension from 8

I like how 0 falls on the 5.

Thoughts:
I think my current code cannot perfectly offset the forces. It could be more interesting if the numbers stayed on their feet longer. Also, I first imagined the numbers kind of bouncing left and right micro-scale (like a person does on one foot) and bumping into one another, but couldn't implement that in time. But I can still somewhat see how the numbers are reluctant to fall on its side, and I like that.
