Okay, maybe this sun ray reflector isn't the world's most practical way to light your home. But if it actually worked well enough even once, I could live with that, because visually speaking, it looks awesome.
In theory, you keep this thing next to a big window that catches sun rays. Then you use the knobs on either side to tilt the mirror housed inside to reflect the light rays up into your house. Worst case scenario, you could just be ironic and keep it in a windowless room. [Fast Company via Ubergizmo]
