With the passage of time, we change.

A short interval of observation creates the illusion of steadiness. For example, within a minute we may witness a constant heartbeat. The tree stands, resolute. Zoom out to a longer time period and change becomes evident. Zoom out more and in a flash of history we see birth, life and death. Zoom out more, civilizations form and disappear. Zoom out more, species come and go, continents are adrift. Zoom out more, way more, stars and planets form, planets may turn into cold rocks, stars explode.

Time is smooth with no natural interval: from the nearly instant to the eon. With our technology we create the tick of time, and with the tick, we record history to time. We celebrate when the big digits change.

On a standard digital clock, the smallest digit changes the fastest. Zero become One. One becomes Two. Two becomes Three. Three becomes Four. Four becomes Five. Five becomes Six. Six becomes Seven. Seven becomes Eight. Eight becomes Nine. Nine becomes Zero. Once every second.

As you figure this work out, time will pass and you will change slightly.

• The light green "state changer" balls indicate that a state change is coming up (a segment of a numeric digit will appear or disappear).

• The dark green "state changer" balls indicate that the state change is complete.

• The maroon "mover" arrows indicate that a segment of a numeric digit is about to move or has moved (for example in the change from a 2 to a 3).

• The maroon "pivoter" triangles indicate that a segment of a numeric digit is about to pivot or has pivoted (for example in the change from a 9 to a 0)
