The combination of technology, design and the more historic 'wallpaper' by Camilla Diedrich is very cool indeed. I like the complex patterns that our home lamps create on the walls and I can see this idea provided related effects. Having light streaming through a room via artistic tracery is a really nice idea and looking at the images - simply beautiful.
I found her work via Daniel Flahif's article on Inhabitat - see the images from that article below.
