In reference to U-Car (Uncertainty Car)

A car which runs in random movement by counting numbers.
I have named it as "Uncertainty Car".
The numbers on the car count from 1 to 9, or 9 to 1.
The counting speed differs individually. Some count slow and some count fast.
The numbers do not indicate "0" (zero).
The reason for this is because it represents the conception of "Ku (like hollowness)" in Buddhist Philosophy.
"O" is also a meaning of "death".
These counting numbers were made as a symbol of "Time: or "Man" based on the following 3 concepts.

1. Keep Changing
2. Connect with Everything
3. Continue for Ever

According to Einsteins' Principle of Relativity, "Time" and "Space" are connected as a link to each other and cannot be separated. Furthermore, according to Heisenberg, the "Time" and "Space" is not absolute but is flexibly controlled by man, or the observer. I wanted to express the relation of the truly universal "Time", "Space" and "Man" which Einstein and Heisenberg had envisioned, by letting the counting numbers run around chaoticly and freely in space.
