The Alliterative Nature of Light and Shadow Spending more time at home over the past year, I noticed details in the exterior of my house and backyard that I had not seen before.

Architecture and nature exist side-by-side, but natural elements often steal the show by drawing attention to their irregular forms and by overlapping and changing engineered structures even in fleeting moments.
