“When a thought takes shape and I begin to visualize it, I create a structure. The structure that emerges while designing grids and drawing wireframes consists of thin lines. These lines are invisible in the finished product, but they have a sculptural quality that is aesthetically pleasing on their own.” - from the description of Byonghak Lee’s solo exhibition: Designing Structure https://leebh.net
