The detail that surprised me most is the strip sitting right in the junction between the dark wall and the ceiling. A continuous diffused run along the whole ceiling perimeter, tucked into that seam, turning cyan and blue. That placement hides the light source completely and leaves just the colour washing across the room. To me that is the single smartest visual decision in the whole setup.
The start-up sequence itself is worth flagging: it came with an update to the WLED controllers, and the maker had wanted exactly that feature for a long time. Watching the room come alive in stages, with the strip above the wall cabinets powering on red while the perimeter run shifts to cyan and blue, is a great payoff. Red and blue ambient light also fills the compartments and the undersides of the wall-mounted shelves, and silhouettes of an office chair and a desk sit in the glow.
On the control side, the maker worked through the WLED app settings until the application made sense, and now every cubby in the shelves can be controlled individually from the app. That level of per-segment control seems like a real advantage for a room-sized install.
One open question: the specific LED models, diffusers, wiring, power supplies, and control boards are not shown anywhere, so anyone hoping to copy the build will have to ask.
