This wall mount light fixture is inspired by Dougong(斗拱),a traditional Chinese architectural element consisted of interlocking wooden brackets. Firstly designed in Rhinoceros, it is made of layers of laser-cut Baltic birch plywood. Assembled in a mortise-and-tenon fashion, it utilizes LED as its light source, while all the wiring, switches, and batteries are hidden within the wooden frames. 
Pieces like this are detachable, concealing switches and batteries inside.
Detachable piece removed, showing interior mechanism.
