MOVING ROCK
& other Moving Sculptures Move the gigantic mass / Minimalist
Moving Rock
11 x 12 x 6 ft（left）
15.5 x 13 x 7.5 ft（right）
I took the molds of the rocks at Central Park, New York City with the permission of Central Park Administration Office.
Large rock took me and 10 helpers, 10 days to take the mold at the Park.
Then I cast the rock with the plastic resin mixed with sand , mica, minerals and pigments.
The plastic resin is very dangerous for the health, so I used the best gas mask connected with air compressor to get fresh air.
I used best materials for the AC motor and switches.
Everything was done very carefully with precise accuracy. 14 and half feet long “Moving Rock” took me two years to complete. I installed permanently these Moving Rocks in several cities in USA.
I believe and hope some of them are still moving every day 10 am-5 pm.
These moving sculptures moves very slowly by the hidden AC motor.
The movement is straight back and forth and very slow. I think myself Minimalist.
Moving Wall (Moves very slowly)
Moving Wall had been exhibited for 10 years but the earthquake damaged it in 2016.
Now it is exhibited as “ The Monument of the 2016 Kumamoto earthquake”
