Two Forms of 'Line'

2019
Earthenware ceramics, Black sand
700Lx500W cm

I chose line as I think it is the purest form, after a dot. I drew a black circle from aquarium sands on the floor. I drew a continuous line in circular revolve then placed the ceramic tiles, which continues in a straight line unit that interacts with the circle. The form of the ceramic line changes when interacting with the ring.
