This simple-looking portable timekeeper is like a complex transformer. It has scales that can set your time and space. You need to set the latitude where you stand, the months, and the approximate date, and then allow the sun to cast. It also has a setting that can adjust the intensity of light cast. The mechanism of this device is still incomprehensible to me, but it is attractive.
I think, I feel this is just so beautiful artwork with ITP way. It seems to use magnetic field liquid, but the way of controlling the movement of the liquid is so beautiful. It is just beautiful; no more words to write.

One is an installation artwork by RICHARD JACKSON, which accurately timed the clocks installed on the four walls and a ceiling so that all the second hands of the clocks make sounds at once, all set for the exact moment. At the exact moment, the sound produced by the hands is quite shouting and feels like a gunshot. It seems to express time as something very powerful, and it seems to be shouting at me to wake up.
In the other installation work by someone's name that I don't remember, there is a difference: all the second hands of a thousand clocks run at different moments. The seconds were sprinkled randomly without pointing time. It made me feel like passing through time instead of allowing me to recognize the interval of one second. It Breaks the rule of the steady flow of the second hands by filling up the temporal gaps using the hands themselves, designed to divide time, spreading time to the spatial venue. I could hardly perceive how long I had stayed in the place; frankly, I didn't try to be aware of how much time passed at that moment. (I experienced this spatial installation in person when I was young. I tried to search for any kind of materials such as photos, videos, and articles of this artwork, but sadly, I could not find anything yet.)
