Radiant Arrays
Explorations of light, geometry & shadow
Making
I. Conception
II. The Ground
III. The Layout
A piece starts as a drawing. Sometimes the geometry arrives whole; more often it takes several attempts before the proportions hold. Then I choose a round. What I want is a clean surface: no knots, no blemishes, no irregular patches. The wood is a ground rather than a subject, which is close to the opposite of how most people who work in wood treat it.
The layout is where a piece's character gets set. Some are built from compass arcs and measured intervals, a logic you could write down and hand to someone else. Convergence Chamber was built that way. Others are placed by eye, marks made quickly and positions chosen by feel. Variable Axis went that way.
IV. Painting & Aperture
V. Hammering
Painting comes before the nails. Most of the colour will disappear under shadow and steel, but it shows in the gaps. Where a piece has a central light source, I drill an aperture through the middle for it.
Then the nails, several hundred at minimum and often far more. A small piece can go from bare round to finished in a day, if the paint cooperates. Others take weeks.
Things go wrong. A knot won't hold a nail, and that one gets adhesive. On pieces where the nails sit very close together, small differences in the angle each one goes in will stop a pattern reading as perfectly regular. Sometimes I fix that by opening up the spacing. Sometimes I leave it, because a field of hand-driven nails that looked machine-made would be a strange thing to want.
A newer group of work replaces the central light source. Individually addressable LED strips run inside the frame, set a fixed distance above the nail surface and hidden behind a wood lip, so the light rakes across the field from the edge rather than radiating from the middle. The strips can be sequenced, which means the shadows move. The first piece is below.
About
I've lived in a lot of places. The western U.S. growing up, then long stretches in New York, East Africa, and Southeast Asia, and now near Geneva, Switzerland. Travel sharpened my eye for pattern: the way forests organise themselves, the geometry of mountains, the shifting behaviour of light across water and stone.
I started working with wood, nails, and pigment in the early 2000s. Günther Uecker's use of the nail as a medium was a direct influence. My sister Kathy Klein (@kathydanmala) and my niece Seffa Klein (@seffaklein) are both artists, and their work is part of how I came to it.
The work that became Radiant Arrays began during the pandemic, out of a craving for something physical and grounding. I started making larger pieces: radial patterns, angled grids, clusters of nails that catch and redirect light. When I saw how shadows could transform a wall, a room, an atmosphere, the direction of everything shifted.
Today each piece is made entirely by hand, from the first pencil mark on wood to the final nail. Using repeated forms and precise patterns, each work becomes a field of shifting shadow and illumination. With connections to both North America and Europe, custom commissions are available throughout these regions.
Beyond the studio, I maintain two off-grid land projects, Adaptation Forest in the northeastern U.S. and Adaptation Island off the coast of Nova Scotia, where I work with forest ecosystems and climate-adaptive design. The same instinct drives both: finding structure in natural systems, and learning what happens when you work with materials honestly and over time.
