I stumbled across Gabriel Dawe's work on Instagram, and I was instantly smitten. He creates hazy geometric clouds that have depth while still appearing insubstantial, like rainbows over the mist of a waterfall.
Dawe makes his installations from thousands of colored threads stretched and woven to create a color gradient that warps to fit each space. Almost every installation is suspended between the floor and the ceiling, so that the vertically-running threads create an illusion like light streaming through a window. Dawe's installations are especially beautiful when they are laced through the empty hollows of stairwells like in "Plexus No. 11" and "Plexus No. 19" (above).
You can see some of Dawe's work below, and even more on his website.
