Coelux has a number of different products, the higher end products like the LC45 you can see a sun in the sky that is pretty amazing. You are looking at around €50,000 after shipping and installation. I didn't end up installing the product because it also requires about 1m of ceiling depth and I didn't want to give up that much space overhead. I ended up using Innerscene which looks better, cheaper, more compact, and has dynamically changing color and moonlight at night.
